[Chromosome substitution and genotype adaptation in Drosophila melanogaster].
The subject of research was the relative adaptability and some of its components (fertility, heat resistance, longevity under the normal conditions and under the conditions of starvation) of the line flies D. melanogaster (C-S, cn, vg) and derived forms received in the result of reciprocal substitution of chromosomes 1, 2 and 3. The experiments performed, showed that the intrusion of the alien chromosomes into the karyotype of analysed line flies caused the decline in adaptability index in the most variants of experiment.
