Question

A) a moth has two alleles for spots. it can have brown or white spots. the brown spot allele frequency is 0.26. what is the white spot allele frequency?

Answer 1

The answer is 0.74.

This is derived using the Hardy Weinburg principle of allelic frequency at equilibrium.

p + q = 1

Therefore if q = 0.26; then 1- 0.26  = 0.74

In most occasions, the allele with the higher frequency is usually the dominant one (but not always).

Answer 2

Answer:

0.74

Explanation:

If the brown spot allele frequency is 0.26 and you want to find out the white spot allele frequency all you have to do is:

1 - 0.26 = 0.74
