(will give brainiest if right) Peppered moths are dark colored when they carry the dominant (D) allele and light colored when they are homozygous for the recessive (d) allele. A population of peppered moths was determined to produce eggs and sperm with the following allele frequencies: 0.15 (D) and 0.85 (d).

What are the genotype frequencies in the offspring of this population? Assume the conditions of Hardy-Weinberg equilibrium apply.

A. DD = 0.0625; Dd = 0.375; dd = 0.5625
B. DD = 0.375; Dd = 0.0625; dd = 0.5625
C. DD = 0.25; Dd = 0.50; dd = 0.25
D. DD = 0.0225; Dd = 0.255; dd = 0.7225

D. DD = 0.0225; Dd = 0.1275; dd = 0.7225

The value of Dd is different in question.

Explanation:

Given -

Dark colored = DD, Dd

light colored = dd

Frequency of allele D = 0.15

Frequency of allele d = 0.85

Hardy-Weinberg equilibrium is applied.

DD = 0.15 X 0.15 = 0.0225

Dd = 0.15 X 0.85 = 0.1275

dd = 0.85 X 0.85 = 0.7225

Therefore, DD = 0.0225; Dd = 0.1275; dd = 0.7225
