2 If a recessive lethal allele has a frequency of 005 in new

2. If a recessive lethal allele has a frequency of 0.05 in newly formed zygotes in one generation, and the locus is in equilibrium, what will be the allele frequency and the genotype frequencies at this locus at the beginning of the next generation and how do you know?

Solution

According to Hardy Weinberg principle

p+q=1

In given question q=.05

Then, p= 1-q = 1-.05= .95

Genotypic frequency:

p^2= .95^2=.9025

2*p*q= 2*.95*.05=.095

q^2= .05^2= .0025
