AIPMT PRELIMS 2005 Zoology Hardy-Weinberg Principle MCQ Question
Type: MCQ-numerical-Medium-Class 12
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
0.16
B
0.48
C
0.36
D
0.24
Correct Answer
Option B
Detailed Explanation
The frequency of heterozygotes (Aa) is calculated using 2pq, where p = 0.6 and q = 0.4. Thus, 2pq = 2(0.6)(0.4) = 0.48.
