Question
In a population of birds, the frequency of the recessive allele for feather coloration (a) is 0.25. Assuming the population is in Hardy-Weinberg equilibrium, calculate the following: The frequency of the dominant allele (A).a.0.25b.0.50c.0.75d.0.15
Solution
The Hardy-Weinberg equilibrium principle states that in a large, random-mating population, the allele and genotype frequencies will remain constant from generation to generation unless acted upon by outside forces.
The sum of all allele frequencies in a population should be 1. In this case, we have two alleles: the dominant allele (A) and the recessive allele (a).
Given that the frequency of the recessive allele (a) is 0.25, we can calculate the frequency of the dominant allele (A) by subtracting the frequency of the recessive allele from 1.
So, the frequency of the dominant allele (A) = 1 - frequency of the recessive allele (a) = 1 - 0.25 = 0.75.
Therefore, the correct answer is c. 0.75.
