We can solve this using the Hardy-Weinberg equilibrium principle.

 

Given:

The frequency of the recessive allele q = 0.25.

 

Step 1: Find p, the frequency of the dominant allele.

Since p + q = 1, we can find p:

p = 1 - q = 1 - 0.25 = 0.75

 

Step 2: Find the frequency of the Homozygous Dominant genotype (BB).

The frequency of the Homozygous Dominant genotype (BB) is given by :
