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.
a) 75
b) 50
c) 25
d) 5​

Answer 1

Answer:

Explanation:

a) 75

Answer 2

Answer:

we can calculate frequency of a

= no of allelic position occupied by a/ total no of allelic positions × 2

= 1/10×2

= 1/20

= 0.05

so no of population= 0.05×100= 5
