please help me understand / solve this question

In a population of aspen trees, there is an allele that codes for a protein required for certain immune responses. The frequency of that allele (M) is 0.92 in the population in generation 1 (time 1). A mutation (allele m) leads to the loss of function of this protein (so, it is deleterious for these aspens). If mutation is acting as the only force for evolution in this population, what would you expect the relative change in frequency of the M allele to be in generation 2 (time 2)? O f(M) will be lower in generation 2 O fM) will only change if selection is also acting in the population O Neither f(M) nor the flm) will change if mutation is the only force of evolution O f(M) will be higher in generation 2

Explanation / Answer

The mutated allele m is deleterious for the aspen trees. So, we can assume that the trees with allele m could not survive and hence the population of trees with this allele will be less in the second generation.

The trees with the allele M have a better chance of survival.

Based on this assumption we can say that the correct answer should be-- f[M] will be higher in generation 2.
