Answer 1

Answer #1

1. - rate of mutation

s-selection coefficient for recessive allele ( frequency)

q^= stable equilibrium

q^ =/s

s= /q^

Frequency of allele changes with mutation rate.

2. Natural selection is based on fitness value. The fitness value for complete selection can be found by selection equation for complete dominance.

q = [pq] [(q)(W₂ - W₁) + (p)(W₁ - W₀)]

W = fitness phenotypes W0=homozygous dominant, W1= heterozygous & W2= homozygous recessive

Change of allele frequency - q

p and q= frequency of dominant and recessive allele.

In complete dominance the change of allele frequency is optimal. And in incomplete dominance, there will be an equilibrium frequency q^.
