Question

In a hardy-weinberg population with two alleles, a and a, that are in equilibrium, the frequency of the allele a is 0.3. what is the frequency of individuals that are homozygous for this allele?in a hardy-weinberg population with two alleles, a and a, that are in equilibrium, the frequency of the allele a is 0.3. what is the frequency of individuals that are homozygous for this allele? 49.0 0.49 9.0 0.9 0.09

Answer 1

0.09 is correct, I took the quiz.

Answer 2

The answer is 0.09.

If an individual is homozygous for an allele a, that means the individual has two alleles a. The frequency of homozygous individual is the square of the frequency of the allele. So, since the frequency of the allele a is 0.3, the frequency of individuals that are homozygous for this allele is 0.3² = 0.09.
