  text: Genetic incompatibilities between two races of the grasshopper Podisma pedestris,
    which differ by a Robertsonian fusion involving the sex chromosome, have been
    investigated. Crosses were made between four populations spanning the chromosomal
    cline; F1 hybrids between the races, though not between separated populations
    of the same race, showed markedly reduced hatching success. Observations of the
    fate of chromosomes transplanted across the cline supported this finding. Crosses
    between grasshoppers from a mixed population in the cline showed a lower average
    hatching success, but no correlation of this inviability with the chromosomal
    polymorphism. The karyotypes of pre-diapause embryos from both types of cross
    gave no evidence for non-disjunction of the sex chromosome trivalent in heterozygous
    females; an upper limit of 16 per cent can be set on the non-disjunction rate.
    These findings suggest that the karyotypic difference is only a weakly selected
    marker for more fundamental changes in genotype.
