Question

A population has two alleles for a given gene, D and d. If the frequency of the dominant allele is 0.45 and the frequency of the recessive allele is 0.55, what will the frequency be for the recessive homozygote genotype?

Answer 1

Answer: 0.30 or 30%

Step-by-step explanation:

According to the Hardy-Weinberg Equilibrium equation, to calculate the percentage of recessive homozygote genotype in the population.

The recessive homozygote genotype (dd) are represented by the q^2 term which equals 0.55 × 0.55 = 0.30 or 30%
