NEET Biology question

At a particular locus, frequency of *A* allele is 0.6 and that of *a* is 0.4. What would be the frequency of heterozygotes in a random mating population at equilibrium?

(A)0.36
(B)0.16
(C)0.24
(D)0.48Correct

Answer: (D)

Solution

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 given Hardy-Weinberg equation: *p*2+2*pq*+*q*2 = 1. were *p*2 =
