Question

If the frequency of homozygous dominant genotype is 0.07 in a randomly mating population, what will be the frequency of the dominant allele?

• A. 0.004
• B. 0.19
• C. 0.38
• D. 0.26

Answer 1

The correct option is D 0.26

So $p^2$ is given as 0.07
Thus the allele frequency will be p = $\sqrt{p^2}$
p = $\sqrt{0.07}$= 0.26
