Question
Consider a gene with two alleles, one dominant, and the other recessive. If this population is in Hardy-Weinberg equilibrium with respect to this gene, what would happen to the dominant allele from generation to generation?Multiple choice question.Its frequency will remain unchangedIts frequency will slowly decreaseIts frequency will slowly increase
Solution
The correct answer is "Its frequency will remain unchanged". According to the Hardy-Weinberg equilibrium principle, allele frequencies in a population will remain constant from generation to generation in the absence of other evolutionary influences. These influences include genetic drift, mutation, selection, gene flow, meiotic drive, genetic hitchhiking, population bottleneck, founder effect and inbreeding.
