## What does P 2 represent in the Hardy-Weinberg equation?

Explanation: In the Hardy-Weinberg equilibrium equation ( p2+2pq+q2=1 ), the term 2pq represents the genotype frequency of heterozygotes (Aa) in a population in equilibrium. The term p2 represents the **frequency of dominant homozygotes (AA)** and the term q2 represents the frequency of recessive homozygotes (aa).

## What is P in Hardy-Weinberg?

p = **frequency of the dominant allele in the population**. q = frequency of the recessive allele in the population. p^{2} = percentage of homozygous dominant individuals. q^{2} = percentage of homozygous recessive individuals. 2pq = percentage of heterozygous individuals.

## What does p2 in the below mentioned Hardy-Weinberg equation indicates ?( P q 2 p2 2pq q2?

Explanation: If 50% of the population carries the recessive allele, then 50% carry the dominant allele. To determine the genotype breakdown we use the equation p^{2} + 2pq + q^{2}, where p^{2} represents homozygous dominant genotype, **2pq represents heterozygous genotype**, and q^{2} represents homozygous recessive genotype.

## Why is the 2 in the term 2pq necessary?

Transcribed image text: In the formula for determining a population’s genotype frequencies, the pq in the term 2pq is necessary **because the population is diploid**. heterozygotes can come about in two ways. the population is doubling in number. heterozygotes have two alleles.

## What do PQ p2 2pq and q2 represent?

p2 +2pq + q2 = 1 Where p2 represents the frequency of the homozygous dominant genotype, q2 represents **the frequency of the recessive genotype** and 2pq is the frequency of the heterozygous genotype.

## How do you calculate p value in Hardy Weinberg?

To calculate the allelic frequencies we simply **divide the number of** S or F alleles by the total number of alleles: 94/128 = 0.734 = p = frequency of the S allele, and 34/128 = 0.266 = q = frequency of the F allele.

## What does the following equation represent explain p2 2pq q2 1?

Evolution. The equation of p^{2} + 2pq + q^{2} = 1 represents **the genotypic frequencies of a population**, when it is in Hardy-Weinberg equilibrium. … The frequency of genotypes, AA is p^{2}, that of aa is q^{2} and that of Aa is 2pq. Hence, p^{2} + 2pq + q^{2} = 1, which is the expansion of (p + q)^{2}.

## Which of the following represents the Hardy-Weinberg equation?

**p2+2pq**.

## Which of the following represents the Hardy-Weinberg equation *?

This is called genetic equilibrium or Hardy-Weinberg equilibrium. It is expressed as **P ^{2} +q^{2} + 2pq = 1**, where p & q denotes the frequencies of different alleles. P is the frequency of allele A & q is the frequency of allele a.
