Verified Solution

Answer & Solution

Correct Answer

(B) \(2pq\)

Step-by-step Solution

Detailed explanation

(b) : In a stable population, for a gene with two alleles, ‘\(A\)’ (dominant) and ‘\(a\)’ (recessive), if the frequency of ‘\(A\)’ is \(p\) and the frequency of ‘\(a\)’ is \(q\), then the frequencies of the three possible genotypes (\(AA, Aa\) and \(aa\)) can be expressed by the Hardy­ Weinberg equation : \(p^2 + 2pq + q^2 = 1\)
