Abstract
Mating activity of 115 wild males was compared with 88 homozygotes and 42 heterozygotes for their second chromosomes. Wild males, 48–96 hours old, inseminated on the average, 4.4±0.1 females per 24 hours. The hetero- and homozygotes for their second chromosomes (other chromosomes being randomly combined with those from the laboratory strain), inseminated on the average 2.8±0.2 and 2.0±0.2 females/24 h. respectively. There is no correlation between homozygotes and heterozygotes for the second chromosome and their wild ancestors which carried these chromosomes. Wild second chromosomes which in homozygous condition produced total sterility of their carriers, and some others which made for an unusually high activity in homozygous males, had on an average similar effects in wild carriers.
