text: The classical infinitesimal model is a simple and robust model for the inheritance
of quantitative traits. In this model, a quantitative trait is expressed as the
sum of a genetic and an environmental component, and the genetic component of
offspring traits within a family follows a normal distribution around the average
of the parents’ trait values, and has a variance that is independent of the parental
traits. In previous work, we showed that when trait values are determined by the
sum of a large number of additive Mendelian factors, each of small effect, one
can justify the infinitesimal model as a limit of Mendelian inheritance. In this
paper, we show that this result extends to include dominance. We define the model
in terms of classical quantities of quantitative genetics, before justifying it
as a limit of Mendelian inheritance as the number, M, of underlying loci tends
to infinity. As in the additive case, the multivariate normal distribution of
trait values across the pedigree can be expressed in terms of variance components
in an ancestral population and probabilities of identity by descent determined
by the pedigree. Now, with just first-order dominance effects, we require two-,
three-, and four-way identities. We also show that, even if we condition on parental
trait values, the “shared” and “residual” components of trait values within each
family will be asymptotically normally distributed as the number of loci tends
to infinity, with an error of order 1/M−−√. We illustrate our results with some
numerical examples.

text: Inversions are structural mutations that reverse the sequence of a chromosome
segment and reduce the effective rate of recombination in the heterozygous state.
They play a major role in adaptation, as well as in other evolutionary processes
such as speciation. Although inversions have been studied since the 1920s, they
remain difficult to investigate because the reduced recombination conferred by
them strengthens the effects of drift and hitchhiking, which in turn can obscure
signatures of selection. Nonetheless, numerous inversions have been found to be
under selection. Given recent advances in population genetic theory and empirical
study, here we review how different mechanisms of selection affect the evolution
of inversions. A key difference between inversions and other mutations, such as
single nucleotide variants, is that the fitness of an inversion may be affected
by a larger number of frequently interacting processes. This considerably complicates
the analysis of the causes underlying the evolution of inversions. We discuss
the extent to which these mechanisms can be disentangled, and by which approach.

text: The term “haplotype block” is commonly used in the developing field of haplotype-based
inference methods. We argue that the term should be defined based on the structure
of the Ancestral Recombination Graph (ARG), which contains complete information
on the ancestry of a sample. We use simulated examples to demonstrate key features
of the relationship between haplotype blocks and ancestral structure, emphasizing
the stochasticity of the processes that generate them. Even the simplest cases
of neutrality or of a “hard” selective sweep produce a rich structure, often missed
by commonly used statistics. We highlight a number of novel methods for inferring
haplotype structure, based on the full ARG, or on a sequence of trees, and illustrate
how they can be used to define haplotype blocks using an empirical data set. While
the advent of new, computationally efficient methods makes it possible to apply
these concepts broadly, they (and additional new methods) could benefit from adding
features to explore haplotype blocks, as we define them. Understanding and applying
the concept of the haplotype block will be essential to fully exploit long and
linked-read sequencing technologies.

text: Differentiated X chromosomes are expected to have higher rates of adaptive
divergence than autosomes, if new beneficial mutations are recessive (the “faster-X
effect”), largely because these mutations are immediately exposed to selection
in males. The evolution of X chromosomes after they stop recombining in males,
but before they become hemizygous, has not been well explored theoretically. We
use the diffusion approximation to infer substitution rates of beneficial and
deleterious mutations under such a scenario. Our results show that selection is
less efficient on diploid X loci than on autosomal and hemizygous X loci under
a wide range of parameters. This “slower-X” effect is stronger for genes affecting
primarily (or only) male fitness, and for sexually antagonistic genes. These unusual
dynamics suggest that some of the peculiar features of X chromosomes, such as
the differential accumulation of genes with sex-specific functions, may start
arising earlier than previously appreciated.

text: The classical infinitesimal model is a simple and robust model for the inheritance
of quantitative traits. In this model, a quantitative trait is expressed as the
sum of a genetic and a non-genetic (environmental) component and the genetic component
of offspring traits within a family follows a normal distribution around the average
of the parents’ trait values, and has a variance that is independent of the trait
values of the parents. Although the trait distribution across the whole population
can be far from normal, the trait distributions within families are normally distributed
with a variance-covariance matrix that is determined entirely by that in the
ancestral population and the probabilities of identity determined by the pedigree.
Moreover, conditioning on some of the trait values within the pedigree has predictable
effects on the mean and variance within and between families. In previous work,
Barton et al. (2017), we showed that when trait values are determined by the sum
of a large number of Mendelian factors, each of small effect, one can justify
the infinitesimal model as limit of Mendelian inheritance. It was also shown that
under some forms of epistasis, trait values within a family are still normally
distributed.

text: We analyse how migration from a large mainland influences genetic load and
population numbers on an island, in a scenario where fitness-affecting variants
are unconditionally deleterious, and where numbers decline with increasing load.
Our analysis shows that migration can have qualitatively different effects, depending
on the total mutation target and fitness effects of deleterious variants. In particular,
we find that populations exhibit a genetic Allee effect across a wide range of
parameter combinations, when variants are partially recessive, cycling between
low-load (large-population) and high-load (sink) states. Increased migration reduces
load in the sink state (by increasing heterozygosity) but further inflates load
in the large-population state (by hindering purging). We identify various critical
parameter thresholds at which one or other stable state collapses, and discuss
how these thresholds are influenced by the genetic versus demographic effects
of migration. Our analysis is based on a ‘semi-deterministic’ analysis, which
accounts for genetic drift but neglects demographic stochasticity. We also compare
against simulations which account for both demographic stochasticity and drift.
Our results clarify the importance of gene flow as a key determinant of extinction
risk in peripheral populations, even in the absence of ecological gradients. This
article is part of the theme issue ‘Species’ ranges in the face of changing environments
(part I)’.

text: "A species distributed across diverse environments may adapt to local conditions.
We ask how quickly such a species changes its range in response to changed conditions.
Szép et al. (Szép E, Sachdeva H, Barton NH. 2021 Polygenic local adaptation in
metapopulations: a stochastic eco-evolutionary model. Evolution75, 1030–1045 (doi:10.1111/evo.14210))
used the infinite island model to find the stationary distribution of allele frequencies
and deme sizes. We extend this to find how a metapopulation responds to changes
in carrying capacity, selection strength, or migration rate when deme sizes are
fixed. We further develop a ‘fixed-state’ approximation. Under this approximation,
polymorphism is only possible for a narrow range of habitat proportions when selection
is weak compared to drift, but for a much wider range otherwise. When rates of
selection or migration relative to drift change in a single deme of the metapopulation,
the population takes a time of order m−1 to reach the new equilibrium. However,
even with many loci, there can be substantial fluctuations in net adaptation,
because at each locus, alleles randomly get lost or fixed. Thus, in a finite metapopulation,
variation may gradually be lost by chance, even if it would persist in an infinite
metapopulation. When conditions change across the whole metapopulation, there
can be rapid change, which is predicted well by the fixed-state approximation.
This work helps towards an understanding of how metapopulations extend their range
across diverse environments.\r\nThis article is part of the theme issue ‘Species’
ranges in the face of changing environments (Part II)’."

text: Many studies have quantified the distribution of heterozygosity and relatedness
in natural populations, but few have examined the demographic processes driving
these patterns. In this study, we take a novel approach by studying how population
structure affects both pairwise identity and the distribution of heterozygosity
in a natural population of the self-incompatible plant Antirrhinum majus. Excess
variance in heterozygosity between individuals is due to identity disequilibrium,
which reflects the variance in inbreeding between individuals; it is measured
by the statistic g2. We calculated g2 together with FST and pairwise relatedness
(Fij) using 91 SNPs in 22,353 individuals collected over 11 years. We find that
pairwise Fij declines rapidly over short spatial scales, and the excess variance
in heterozygosity between individuals reflects significant variation in inbreeding.
Additionally, we detect an excess of individuals with around half the average
heterozygosity, indicating either selfing or matings between close relatives.
We use 2 types of simulation to ask whether variation in heterozygosity is consistent
with fine-scale spatial population structure. First, by simulating offspring using
parents drawn from a range of spatial scales, we show that the known pollen dispersal
kernel explains g2. Second, we simulate a 1,000-generation pedigree using the
known dispersal and spatial distribution and find that the resulting g2 is consistent
with that observed from the field data. In contrast, a simulated population with
uniform density underestimates g2, indicating that heterogeneous density promotes
identity disequilibrium. Our study shows that heterogeneous density and leptokurtic
dispersal can together explain the distribution of heterozygosity.

text: Local adaptation leads to differences between populations within a species.
In many systems, similar environmental contrasts occur repeatedly, sometimes driving
parallel phenotypic evolution. Understanding the genomic basis of local adaptation
and parallel evolution is a major goal of evolutionary genomics. It is now known
that by preventing the break-up of favourable combinations of alleles across multiple
loci, genetic architectures that reduce recombination, like chromosomal inversions,
can make an important contribution to local adaptation. However, little is known
about whether inversions also contribute disproportionately to parallel evolution.
Our aim here is to highlight this knowledge gap, to showcase existing studies,
and to illustrate the differences between genomic architectures with and without
inversions using simple models. We predict that by generating stronger effective
selection, inversions can sometimes speed up the parallel adaptive process or
enable parallel adaptation where it would be impossible otherwise, but this is
highly dependent on the spatial setting. We highlight that further empirical work
is needed, in particular to cover a broader taxonomic range and to understand
the relative importance of inversions compared to genomic regions without inversions.

text: Maternally inherited Wolbachia transinfections are being introduced into natural
mosquito populations to reduce the transmission of dengue, Zika and other arboviruses.
Wolbachia-induced cytoplasmic incompatibility provides a frequency-dependent reproductive
advantage to infected females that can spread transinfections within and among
populations. However, because transinfections generally reduce host fitness, they
tend to spread within populations only after their frequency exceeds a critical
threshold. This produces bistability with stable equilibrium frequencies at both
0 and 1, analogous to the bistability produced by underdominance between alleles
or karyotypes and by population dynamics under Allee effects. Here, we analyze
how stochastic frequency variation produced by finite population size can facilitate
the local spread of variants with bistable dynamics into areas where invasion
is unexpected from deterministic models. Our exemplar is the establishment of
wMel Wolbachia in the Aedes aegypti population of Pyramid Estates (PE), a small
community in far north Queensland, Australia. In 2011, wMel was stably introduced
into Gordonvale, separated from PE by barriers to Ae. aegypti dispersal. After
nearly six years during which wMel was observed only at low frequencies in PE,
corresponding to an apparent equilibrium between immigration and selection, wMel
rose to fixation by 2018. Using analytic approximations and statistical analyses,
we demonstrate that the observed fixation of wMel at PE is consistent with both
stochastic transition past an unstable threshold frequency and deterministic transformation
produced by steady immigration at a rate just above the threshold required for
deterministic invasion. The indeterminacy results from a delicate balance of parameters
needed to produce the delayed transition observed. Our analyses suggest that once
Wolbachia transinfections are established locally through systematic introductions,
stochastic “threshold crossing” is likely to only minimally enhance spatial spread,
providing a local ratchet that slightly – but systematically – aids area-wide
transformation of disease-vector populations in heterogeneous landscapes.

text: When Mendel’s work was rediscovered in 1900, and extended to establish classical
genetics, it was initially seen in opposition to Darwin’s theory of evolution
by natural selection on continuous variation, as represented by the biometric
research program that was the foundation of quantitative genetics. As Fisher,
Haldane, and Wright established a century ago, Mendelian inheritance is exactly
what is needed for natural selection to work efficiently. Yet, the synthesis remains
unfinished. We do not understand why sexual reproduction and a fair meiosis predominate
in eukaryotes, or how far these are responsible for their diversity and complexity.
Moreover, although quantitative geneticists have long known that adaptive variation
is highly polygenic, and that this is essential for efficient selection, this
is only now becoming appreciated by molecular biologists—and we still do not have
a good framework for understanding polygenic variation or diffuse function.

text: Maternally inherited Wolbachia transinfections are being introduced into natural
mosquito populations to reduce the transmission of dengue, Zika, and other arboviruses.
Wolbachia-induced cytoplasmic incompatibility provides a frequency-dependent reproductive
advantage to infected females that can spread transinfections within and among
populations. However, because transinfections generally reduce host fitness, they
tend to spread within populations only after their frequency exceeds a critical
threshold. This produces bistability with stable equilibrium frequencies at both
0 and 1, analogous to the bistability produced by underdominance between alleles
or karyotypes and by population dynamics under Allee effects. Here, we analyze
how stochastic frequency variation produced by finite population size can facilitate
the local spread of variants with bistable dynamics into areas where invasion
is unexpected from deterministic models. Our exemplar is the establishment of
wMel Wolbachia in the Aedes aegypti population of Pyramid Estates (PE), a small
community in far north Queensland, Australia. In 2011, wMel was stably introduced
into Gordonvale, separated from PE by barriers to A. aegypti dispersal. After
nearly 6 years during which wMel was observed only at low frequencies in PE, corresponding
to an apparent equilibrium between immigration and selection, wMel rose to fixation
by 2018. Using analytic approximations and statistical analyses, we demonstrate
that the observed fixation of wMel at PE is consistent with both stochastic transition
past an unstable threshold frequency and deterministic transformation produced
by steady immigration at a rate just above the threshold required for deterministic
invasion. The indeterminacy results from a delicate balance of parameters needed
to produce the delayed transition observed. Our analyses suggest that once Wolbachia
transinfections are established locally through systematic introductions, stochastic
“threshold crossing” is likely to only minimally enhance spatial spread, providing
a local ratchet that slightly—but systematically—aids area-wide transformation
of disease-vector populations in heterogeneous landscapes.

text: 'Selection accumulates information in the genome—it guides stochastically
evolving populations toward states (genotype frequencies) that would be unlikely
under neutrality. This can be quantified as the Kullback–Leibler (KL) divergence
between the actual distribution of genotype frequencies and the corresponding
neutral distribution. First, we show that this population-level information sets
an upper bound on the information at the level of genotype and phenotype, limiting
how precisely they can be specified by selection. Next, we study how the accumulation
and maintenance of information is limited by the cost of selection, measured as
the genetic load or the relative fitness variance, both of which we connect to
the control-theoretic KL cost of control. The information accumulation rate is
upper bounded by the population size times the cost of selection. This bound is
very general, and applies across models (Wright–Fisher, Moran, diffusion) and
to arbitrary forms of selection, mutation, and recombination. Finally, the cost
of maintaining information depends on how it is encoded: Specifying a single allele
out of two is expensive, but one bit encoded among many weakly specified loci
(as in a polygenic trait) is cheap.'

text: Reproductive isolation (RI) is a core concept in evolutionary biology. It
has been the central focus of speciation research since the modern synthesis and
is the basis by which biological species are defined. Despite this, the term is
used in seemingly different ways, and attempts to quantify RI have used very different
approaches. After showing that the field lacks a clear definition of the term,
we attempt to clarify key issues, including what RI is, how it can be quantified
in principle, and how it can be measured in practice. Following other definitions
with a genetic focus, we propose that RI is a quantitative measure of the effect
that genetic differences between populations have on gene flow. Specifically,
RI compares the flow of neutral alleles in the presence of these genetic differences
to the flow without any such differences. RI is thus greater than zero when genetic
differences between populations reduce the flow of neutral alleles between populations.
We show how RI can be quantified in a range of scenarios. A key conclusion is
that RI depends strongly on circumstances—including the spatial, temporal and
genomic context—making it difficult to compare across systems. After reviewing
methods for estimating RI from data, we conclude that it is difficult to measure
in practice. We discuss our findings in light of the goals of speciation research
and encourage the use of methods for estimating RI that integrate organismal and
genetic approaches.

text: 'This paper analyzes the conditions for local adaptation in a metapopulation
with infinitely many islands under a model of hard selection, where population
size depends on local fitness. Each island belongs to one of two distinct ecological
niches or habitats. Fitness is influenced by an additive trait which is under
habitat-dependent directional selection. Our analysis is based on the diffusion
approximation and accounts for both genetic drift and demographic stochasticity.
By neglecting linkage disequilibria, it yields the joint distribution of allele
frequencies and population size on each island. We find that under hard selection,
the conditions for local adaptation in a rare habitat are more restrictive for
more polygenic traits: even moderate migration load per locus at very many loci
is sufficient for population sizes to decline. This further reduces the efficacy
of selection at individual loci due to increased drift and because smaller populations
are more prone to swamping due to migration, causing a positive feedback between
increasing maladaptation and declining population sizes. Our analysis also highlights
the importance of demographic stochasticity, which exacerbates the decline in
numbers of maladapted populations, leading to population collapse in the rare
habitat at significantly lower migration than predicted by deterministic arguments.'

text: If there are no constraints on the process of speciation, then the number
of species might be expected to match the number of available niches and this
number might be indefinitely large. One possible constraint is the opportunity
for allopatric divergence. In 1981, Felsenstein used a simple and elegant model
to ask if there might also be genetic constraints. He showed that progress towards
speciation could be described by the build‐up of linkage disequilibrium among
divergently selected loci and between these loci and those contributing to other
forms of reproductive isolation. Therefore, speciation is opposed by recombination,
because it tends to break down linkage disequilibria. Felsenstein then introduced
a crucial distinction between “two‐allele” models, which are subject to this effect,
and “one‐allele” models, which are free from the recombination constraint. These
fundamentally important insights have been the foundation for both empirical and
theoretical studies of speciation ever since.
