## What is p2 in Hardy-Weinberg?

In the equation, p^{2} represents **the frequency of the homozygous genotype AA**, q^{2} represents the frequency of the homozygous genotype aa, and 2pq represents the frequency of the heterozygous genotype Aa.

## What does p2 represent in the equation?

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.

## What does p2 in the below mentioned Hardy-Weinberg equation indicate 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.

## How do you calculate P and Q?

We can calculate the values of p and q, in a representative sample of individuals from a population, by **simply counting the alleles and dividing by the total number of alleles examined**. For a given allele, homozygotes will count for twice as much as heterozygotes.

## 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 does q2 mean?

A quarter refers to one-fourth of a year and is typically expressed as Q1 for the first quarter, Q2 for the second quarter, and so **forth**.

## What does the term PQ represent in the Hardy-Weinberg formula?

Each term in the equation represents one genotype frequency. The frequency of the homozygous dominant genotype is p squared, and the homozygous recessive is represented by q squared. The **heterozygous genotype** is two pq.

## What does P represent in the Hardy Weinberg principle quizlet?

P= **Dominant allele/total amount**. **Only $47.88/year**. How would you find the freq of the q (recessive) allele. Q= Recessive allele/total amount. What is the hardy weinberg equation?

## What does PQ represent in the equation?

In the Hardy-Weinberg equilibrium equation, the term 2pq represents the **genotype frequency of heterozygotes in a population in equilibrium** (where p2 + 2pq + q2 = 1 ).

## What is the frequency of heterozygous individual in Hardy Weinberg equation?

The frequency of the dominant allele. Answer: Since q = 0.2, and p + q = 1, then p = 0.8 (80%). The frequency of heterozygous individuals. Answer: The frequency of heterozygous individuals is **equal to 2pq**.

## How do gene frequencies behave in Hardy-Weinberg equilibrium?

When a population is in Hardy-Weinberg equilibrium for a gene, **it is not evolving**, and allele frequencies will stay the same across generations. There are five basic Hardy-Weinberg assumptions: no mutation, random mating, no gene flow, infinite population size, and no selection.
