A recessive disorder affects 1 in 10,000 individuals. Under HWE, the carrier frequency (heterozygotes) is approximately
- A
1 in 10,000
- B
1 in 5,000
- C
1 in 100
- Dcheck_circle
1 in 50
Explanation
q² = 1/10000 → q = 0.01. p ≈ 1, so 2pq ≈ 2(0.01) = 0.02 = 1/50. Carriers are far more common than affected individuals.
