Abstract

The model of isogenous strains with chromosome substitutions has been used to estimate the relative contributions of the X chromosome and autosomes (chromosomes 2 and 3) to the control of some mating behavior traits in Drosophila melanogaster. It has been found that the male sexual activity (SA), female sexual receptivity (SR), and copulation latency (CL) are determined by interaction between X-chromosome and autosomal genes, whereas the copulation duration (CD) is mainly controlled by the X-chromosome genes. The synthesized isogenous strains have been shown to be more similar to hybrids than to the original strains. In the offspring with hybrid genotypes, the relationships between all traits are less stable, which may be related with an increase in the heterozygosity level and changes in genetic homeostasis.
