Question

Calculate allele frequency: If there are 40 butterflies in a population and 27 of them are yellow, what is the yellow allele frequency?

Answer 1

Answer:

The frequency of the yellow allele in the 40 butterflies is:

• 0.675  %

Explanation:

The allelic frequency or genetic frequency is the variant of a gene found in a population.

The sum of the variants of the recessive gene with the normal ones of the population of the dominant gene give 1 (Or 100% of the population)

If a group of 40 butterflies has a dominant gene that makes them yellow, then:

Yellow: Aa. That is the dominant color of butterflies.

Another color: aa. That would the recessive color be in the butterflies.

• Aa : 27/40 = 0.675

• aa : 13/40 = 0.325
