ANALYSIS OF IRRADIATED DROSOPHILA POPULATIONS FOR MEIOTIC DRIVE
Irradiated populations of Drosophila were analyzed for the existence of chromosomes or alleles represented in the gametes of a heterozygote with a frequency greater than the expected 50%. Such phenomena have been referred to as cases of meiotic drive when the basis is found in some aberration of meiosis. Chromosomes were tested for about 200 generations. The genetic tests consisted of back-crossing heterozygotes for chromosomes derived from the irradiated populations and for stock chromosomes carrying mutant genes to the mutant stock in order to detect any deviation in the progeny from the expected 50% of each type. Of 1654 tests there were two instances in which the chromosomes derived from the irradiated population were recovered in significantly more than half the progeny, and where this deviation persisted after repeated testing.
