Six of these loci showed widespread polymorphism, and a further eleven had very little or no variation. Two loci (Idh, 6Pgd) had rare alleles in different frequencies in the two areas surveyed. The remaining two loci (Mdh-1, Mdh-2) showed a marked increase in the frequency of rare variants, from 1 per cent outside the hybrid zone, up to 5 per cent at its centre. This region of increased electrophoretic variation coincided with the chromosomal cline between the two races, and with a region of decreased viability. It was spread over about the same width as the chromosomal cline. Possible explanations for this extra variation include intragenic recombination and elevated mutation rates.","lang":"eng"}],"publication_status":"published","date_published":"1983-04-01T00:00:00Z","extern":"1","issue":"2","article_processing_charge":"No","month":"04","date_updated":"2022-01-25T14:07:12Z","type":"journal_article","day":"01","acknowledgement":"We would like to thank Manse East, Lynda Flegg, and Sim Webb for their excellent technical assistance, and Prof. J.
