Abstract

A comparative analysis of the phenotypic values of the proximal and distal fragments of the radial wing vein was carried out in heterogeneous lines of Drosophila melanogaster and in isogenic lines derived from them with the help of a balancer line. The mean values of the traits in the isogenic lines were shown to significantly differ from the corresponding values in the “parental” heterogeneous lines. Apparently, the change in the trait values was caused by a double recombination exchange between the inverted and the “normal” chromosomes, which suggests partial crossing over suppression in the balancer lines.
