Abstract

Significant differences among cage populations of Drosophila in the dynamics of linkage disequilibrium for marker loci b, cn and vg of chromosome 2 have been found at optimum and extreme temperatures. Fifteen generations of selection under extreme conditions considerably increased recombination frequency in the cn-vg region and over the whole of the b-vg interval. From the data obtained it is inferred that recombination-promoting alleles with intermediate expression in the heterozygous state are responsible for these changes.
