  text: Populations of the grasshopper Podisma pedestris were collected from two ends
    of a zone of hybridization between two chromosome races, at Seyne and Tende in
    southern France. 21 enzyme and protein loci were detected by gel electrophoresis.
    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.
