Freq of autosomal recesive lethal gene is 0.4.find d freq of carrier in a population of 200 individuals.....Ans: 96

Question

Arun · Answer

The frequency of the recessive allele is q = 0.4 (given)
Hence, p = 1-0.4 = 0.6 (as p = 1- q)
According to Hardy- Weinberg principle, p² + ?2pq + q² = 1.
hnce, p² = (0.6)² => 0.36
q² = (0.4)² => 0.16
2pq = 0.48
since, 2pq is the frequency of hetrozygous carrier,
= 0.48 X 200
=> 96 Individuals
