हिन्दीA gene locus has two alleles A, a. If the frequency of dominant allele A is 0.4, then what will be the frequency of homozygous dominant, heterozygous and homozygous recessive individuals in the population?
View Answer & Solution
Correct answer · Option A
0.16 (AA); 0.48 (Aa); 0.36 (aa)
Explanation
Given \( p = 0.4 \) (frequency of A), so \( q = 1 - 0.4 = 0.6 \). Frequencies: \( p^2 = (0.4)^2 = 0.16 \), \( 2pq = 2(0.4)(0.6) = 0.48 \), \( q^2 = (0.6)^2 = 0.36 \).
