what does the term 2pq represent in the hardy-weinberg equation? the frequency of homozygous recessive individuals the frequency
Nostrana [21]

The term 2pq represented in the hardy-weinberg equation is the frequency of heterozygotes and is denoted as option D.

<h3>What is Hardy-weinberg equation?</h3>

This mathematical equation is used to calculate the genetic variation of a population at equilibrium and can be seen below:

p² + 2pq + q² = 1

where

p² is dominant homozygous frequency (AA)

2pq is heterozygous frequency (Aa)

q² is recessive homozygous frequency (aa).

The 2pq can be seen as the heterozygous frequency which is therefore the reason why option D which is frequency of heterozygotes was chosen as the most appropriate choice.
