If the frequency of a dominant phenotype in a stable population is 75%, the frequency of recessive allele in that population would be

A

0.375

B

0.75

C

0.094

D

0.5

Text Solution

Verified by Experts

The correct Answer is:
D
The given frequency of a dominant phenotype is 75% and, therefore, its recessive will be 25%. 75:25 i.e, 3:1 ratio which is AA,Aa,Aa,aa. Here allele A: a is 4:4 i.e., 50:50.
