To evaluate the evolutionary dynamics and selective forces governing competition between the white-eye mutant gene and its normal wild-type allele in laboratory populations of Drosophila.
Established experimental laboratory populations of Drosophila containing both white-eye mutant and wild-type alleles.
Tracked allele and phenotype frequencies over successive generations under controlled environmental competition.
Wild-type alleles demonstrated a significant selective advantage over the white-eye mutant gene during population competition.
White-eye allele frequencies progressively decreased across generations, reflecting reduced biological fitness and reproductive success relative to wild-type flies.
