Abstract

A comparative analysis of dysgenic traits of P-M-like strains containing retrotransposon Penelope in D. virilis was carried out. Main characteristics of hybrid dysgenesis in offsprings of the first and second generation of dysgenic traits were studied: the level of gonadal reduction, the imago sterility, the availability of recombination events in males and sex chromosomes non-disjunction, the mutations and morphosis spectrum. The presence of retrotransposon Penelope copies in the tested strain was detected and the availability of Penelope shown to be a necessary but not determinative factor in forming certain features of hybrid dysgenesis.
Keywords: hybrid dysgenesis, dysgenic recombination, gonadal reduction, retrotransposon Penelope
