A population shows two phenotypes for a trait controlled by one locus with complete dominance.
Assuming Hardy-Weinberg equilibrium, what is the frequency of the recessive allele q?
- Acheck_circle
0.6
- B
0.36
- C
0.24
- D
0.4
Explanation
Recessive phenotype frequency equals q² = 0.36. Therefore q = sqrt(0.36) = 0.6.
