In a population of yellow mushrooms, a mutation resulted in a new purple type of mushroom that herbivores avoided. Because herbivores avoided the purple mushrooms, they were able to spread more spores and increased to make up 1% of the population. In one year, however, flash flood killed all of the purple mushrooms in the population, leaving only a few yellow mushrooms alive. Identify which evolutionary mechanism was responsible for the fixation of the yellow mushroom genotype in this population. Select one: a. Mutation b. Genetic drift c. Non-random mating Ⓒd. Natural selection * Gene flow e.
