title: [The effect of the genotype on the expressiveness of the vestigial trait and polyteny of chromosomes in Drosophila melanogaster Meig].
abstract: The effects of the Bar (B) and white (w) mutations on the expressiveness of the character vestigial (vg) and the degree of polyteny of salivary gland giant chromosomes were studied in Drosophila melanogaster. Either mutation changed both the expressiveness of vestigial and the degree of chromsome polyteny. A negative association between the vg expressiveness and the degree of chromosome polyteny was revealed and proved to be stronger in females than in males. The parameters under study were shown to differ between females and males.
