A population of diploid organisms is at Hardy-Weinberg equilibrium. If the frequency of allele A is 0.1, the frequency of AA is ___________.
[Re-NEET 2026]
✓ Correct answer: a)
0.01
Explanation
For a population in Hardy–Weinberg equilibrium:
\({p}^{2}+2pq+{q}^{2}=1\)Where:
- \(p\) = frequency of allele A
- \(q\) = frequency of allele a
- \({p}^{2}\) = frequency of genotype AA
- \(2pq\) = frequency of genotype Aa
- \({q}^{2}\) = frequency of genotype aa
Given: \(p=0.1\)
Frequency of AA genotype: \(AA={p}^{2}\)\(=(0.1{)}^{2}\)\(=0.01\)
Therefore, the frequency of AA = 0.01.
Correct Answer: Option A (0.01)
