ABSTRACT
Experiment was conducted on Drosophila simulans to isolate and characterize mutants induced by 3000 r gamma radiation. Irradiated young males (2-3 days old) were crossed to controlled virgin female flies. F1, F2 and F3 generations were examined to identify visible mutations. A total of six induced mutant flies were isolated from the irradiated strains. Four out of the six mutants were cultured successfully and their genetic pattern was studied, while the remaining two mutants could not be cultured due to unavoidable circumstances. The cultured mutants were composed of one sex-linked recessive, and three autosomals (two autosomal recessive and one autosomal dominant). No spontaneous mutant fly could be found in controlled strain maintained for comparison.
