Consider a locus with two alleles in a population of 100 individuals, with the initial frequencies A1 = 0.7 and A2 = 0.3. If A1 and A2 are selectively neutral, what is the probability that the A2 allele will drift to fixation?

probability that the A2 allele will drift to fixation is 30%

Explanation:

given data

population = 100

initial frequencies A1 = 0.7

initial frequencies A2 = 0.3

solution

we know that initial A1 frequency and A2 frequency and here the fixation time is referred as amount of time

so it take to fix allele in a certain population

and A1 & A2 is neutral for fixation

so that here fixation probability

it is neutral so change allelic frequency by the no chance of the occurrence of an mutation

so here probability that the A2 allele will drift to fixation is

A2 allele will drift to fixation = A2 * 100 ... 1

A2 allele will drift to fixation = 0.3 * 100

A2 allele will drift to fixation = 30%

so correct answer is 30%
