Question 11 of 30
Under ideal conditions, how do allele frequencies change over time?
A. The frequency of the recessive allele increases in each generation.
B. The allele frequency does not change from one generation to the
next.
C. The frequency of the dominant allele increases in each generation.
O D. The alleles eventually reach a 50/50 balance.

Answer 1

The frequency of the dominant allele increases in each generation. Thus, the correct option is C.

What is natural selection?

Natural selection is a process in which more environment-adapted organisms tend to survive and reproduce more frequently than less environment-adapted ones.

Because rare alleles are typically found in heterozygotes, the initial increase in frequency of a rare, advantageous, dominant allele is faster than that of a rare, advantageous, recessive allele. Therefore, natural selection won't be able to "see" a new recessive mutation until it is prevalent enough to manifest in homozygotes.

Once a population is in Hardy-Weinberg equilibrium, its frequency distribution won't vary from generation to generation.
