Answer:
The answer to the question is
The expected frequency of homozygotes for the allele in a population at Hardy-Weinberg Equilibrium is 0.998
Explanation:
From the question, we have the frequency of an allele = 0.999
By Hardy-Weinberg Equilibrium
p² + 2pq + q² = 1 and p + q = 1
p = dominant allele frequency in the population
q = recessive allele frequency in the population
p² = homozygous dominant individuals percentage
q² = homozygous recessive individuals percentage
2pq = heterozygous individuals percentage
Therefore the frequency of the homozygotes for the allele = 0.999² = 0.998001 ≅ 0.998 to three decimal places
The Hardy-Weinberg equilibrium states that the genetic disparity in a population will remain unchanged from generation to generation in the absence of evolutionary disturbing influences
