Question

A sunflower population in Hardy-Weinberg equilibrium has the following allele frequencies for petal color: 0.75 dominant, 0.25 recessive. If the assumptions of Hardy-Weinberg equilibrium continue to hold, then after 200 generations:

A. The allele frequencies will be: 0.75 dominant and 0.25 recessive.

B. The allele frequencies will be: 0.50 dominant and 0.50 recessive.

C. The allele frequencies will be: 1.0 dominant and 0 recessive.

D. There is no way to predict allele frequencies, given the information provided.

Explanation / Answer

The Hardy–Weinberg equilibrium, model states that allele and genotype frequencies in a population will remain constant from generation to generation in the absence of other evolutionary influences.

A. The allele frequencies will be: 0.75 dominant and 0.25 recessive.
