NEET Zoology Natural Selection MCQ Question
Type: MCQ-numerical-Medium-Class 12
In a population of diploid organisms, if the frequency of allele A (p) is 0.6, what is the expected frequency of heterozygous individuals (Aa) according to Hardy-Weinberg equilibrium?
A
0.24
B
0.36
C
0.48
D
0.64
Correct Answer
Option C
Detailed Explanation
The frequency of heterozygous individuals (Aa) is given by 2pq, where p is the frequency of allele A and q is the frequency of allele a (q = 1 - p). Here, p = 0.6 and q = 0.4, so 2pq = 2 * 0.6 * 0.4 = 0.48.
