Abstract excerpt
Drosophila melanogaster females homozygous for X-linked recessive markers, y and wi, were exposed to CO2 and mated with y+ w+/Y males. The progeny were sampled and inspected for y wi/y wi/Y (XXY) and y+ w+/O (XO) mutants. The frequency of nondisjunction XXY mutants after a 90-min exposure to CO2 increased 100-fold above the control level in the first-day brood but did not increase above the control level in the...
