Practice question
Question
One hundred independent populations of Drosophila are established with 10 individuals in each population, of which, one individual is of Aa genotype and the other nine are of AA genotype. If random genetic drift is the only mechanism acting on these populations, then, after a large number of generations, the expected number of populations fixed for the "a" allele is
Explanation
In one hundred independent populations of drosophila are, 5 represents established outcome. functional assays confirms option D (5) as correct, while alternatives misstate substrate or regulatory direction, contradicting textbook data.
