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?

Solution

Answer: 30%

Reason:

The gene locus with two alleles in a population of 100 individuals, with initial A frequency is 0.7 whereas A2 frequency is 0.3 the fixation time is referred as amount of time it will take to fix a allele in a certain population. However, given the A1 & A2 are neutral for fixation so that the fixation probability i snot going to change with allelic frequency due to no chance of \"occurrence of mutation\" since it is neutral therefore, A2 * 100 --> 0.3 * 100 --> 30%
