The effects of genotype of the laboratory strains, C(1)DX, ywf/Y, 23.5 MRF/CyL 4, and C(1)DX,yf; π2, on locus-specific instability in the yellow gene of the strains y 2-217, y 2-715, and y 2-700 from Uman’ population of Drosophila melanogaster was studied. Crosses of the males from Uman’-derived lines with the C(1)DX,ywf/Y females yielded a cascade of derivatives, mostly consisting of y + and y 2 alleles, while their crosses with the 23.5 MRF/CyL 4 and C(1)DX,yf; π2 females mostly resulted in the appearance of y + and y 1 derivatives. The genomes of laboratory strains used in the study contained the full-sized hobo elements, which could differ from one another relative to the structure of variable region and affinity to different DNA sequences.
