Answer #1

Ans) equilibrium frequency of recessive allele=0.43

Solution :
s =selection coefficient for homozygous dominant= 0.3
t = selection coefficient for homozygous recessive=0.4


To estimate the equilibrium frequency of recessive allele:

q'= selection coefficient for homozygous dominant /(selection coefficient for homozygous dominant + selection coefficient for homozygous recessive)

q'= equilibrium freq of recessive allele=s/(s+t)=0.3/(0.3+0.4)=0.3/0.7=0.43

The equilibrium frequency of recessive allele=0.43
