Imagine a population evolving by genetic drift in which the frequency of allele K is 0.2. What is the probability that at some point in the future allele K will drift to a frequency of 1?

Solution

Answer:

The probability that a particular allele will be fixed in a population in the future equals the frequency of the allele in the population.

If there are two alleles in a population, A and a, with frequencies p and q, the probability that the allele a will be lost at some point in the future is p and the probability that allele A will be lost is q.

In this case, a population evolving by genetic drift in which the frequency of allele K is 0.2.

There is the 20% probability that at some point in the future allele K will drift to a frequency of 1.
