Answer:
B) when the frequency of dominant alleles is equal to the frequency of recessive alleles
Explanation:
The equation for Hardy–Weinberg equilibrium is:
[tex]p^{2} +2pq+q^{2}[/tex];
where p=frequency of dominant alleles; q=frequency of recessive alleles and 2pq is the number of heterozygotes.
So, in order to maximize 2pq, p must be equal to q, and because p-q=1, we can conclude that 2pq max = 2*0.5*0.5=0.5 or 50%
A) when the frequency of dominant alleles is more than the frequency of recessive alleles: Homozygous dominant will be prevalent
C) when the frequency of dominant alleles is less than the frequency of recessive alleles: Homozygous recessive will be prevalent
