A population is in Hardy-Weinberg equilibrium for a trait with alleles A and a. If the frequency of allele A is 0.6, what will be the frequency of heterozygotes in the next generation?
Correct: C
In Hardy-Weinberg equilibrium, heterozygote frequency is 2pq. Here, p = 0.6, q = 0.4. 2pq = 2 × 0.6 × 0.4 = 0.48. Correct option is C.
