The allele for red spots (B) in a certain butterfly species is dominant over the allele for blue spots (b). One population of this species that you’re studying has 500 butterflies, and 237 of them have blue spots.

What is the frequency of the dominant allele (B)?

What is the frequency of the recessive allele (b)?

How many total heterozygous butterflies are there in the population?

Answer has been attached below

Frequency of B = 0.68

Frequency of b = 0.32

Total heterozygote butterflies ( Bb) = 217
