(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

it provides an alternative energy pathway for the reaction to proceed.

a catalyst is a substance that speeds up the rate of a chemical reaction but is not consumed during the course of the reaction.

catalysts increase the rate of reaction without being used up. they do this by lowering the activation energy needed. with a catalyst, more collisions result in a reaction, so the rate of reaction increases. different reactions need different catalysts.

a catalyst works by providing an alternative reaction pathway to the reaction product. the rate of the reaction is increased as this alternative route has a lower activation energy than the reaction route not mediated by the catalyst.
