# What do p and q represent in the Hardy-Weinberg equilibrium equation?

## What do p and q represent in the Hardy-Weinberg equilibrium equation?

The Hardy-Weinberg equation is a mathematical equation that can be used to calculate the genetic variation of a population at equilibrium. where p is the frequency of the “A” allele and q is the frequency of the “a” allele in the population.

What does Q represent in Hardy-Weinberg?

The Hardy-Weinberg Law is an equation for calculating the frequencies of different alleles and genotypes in a population in genetic equilibrium and expressed by the formula p + q = 1 where p is the frequency of the dominant allele and q is the frequency of the recessive allele.

Why is there a 2 in the Hardy-Weinberg equation?

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).

### How do you calculate P and Q?

To find q, simply take the square root of 0.09 to get 0.3. Since p = 1 – 0.3, then p must equal 0.7. 2pq = 2 (0.7 x 0.3) = 0.42 = 42% of the population are heterozygotes (carriers)….

1. The frequency of the recessive allele.
2. The frequency of the dominant allele.
3. The frequency of heterozygous individuals.

What does the Q represent in the Hardy-Weinberg equation quizlet?

The p represents the frequency of the dominant allele. The q represents the frequency of the recessive allele.

What do P and Q stand for in the Hardy-Weinberg equation quizlet?

What does p stand for in the Hardy-Weinberg equation? The dominant allele. What does q stand for in the Hardy-Weinberg equation? The recessive allele.

## How do you use the Hardy Weinberg Theorem?

The Hardy-Weinberg equation used to determine genotype frequencies is: p2 + 2pq + q2 = 1. Where ‘p2’ represents the frequency of the homozygous dominant genotype (AA), ‘2pq’ the frequency of the heterozygous genotype (Aa) and ‘q2’ the frequency of the homozygous recessive genotype (aa).

What does the Hardy Weinberg principle predict?

The Hardy–Weinberg principle provides a mathematical model, which predicts that allele frequencies will not change from generation to generation.

Is P or Q recessive?

In the simplest system, with two alleles of the same locus (e.g. A,a), we use the symbol p to represent the frequency of the dominant allele within the population, and q for the frequency of the recessive allele.

### Why does the Hardy Weinberg equation equal 1?

They reasoned that the combined frequencies of p and q must equal 1, since together they represent all the alleles for that trait in the population: One value of the Hardy-Weinberg equilibrium equation is that it allows population geneticists to determine the proportion of each genotype and phenotype in a population.

How do you find P and Q in a quadratic equation?

p and q are the x-intercepts or solutions of the quadratic equation. For example, consider the quadratic equation (x + 4)(x – 4) = 0. Its solutions are -4 and 4 because the numbers in place of p and q in this equation are -4 and 4.

How can the Hardy-Weinberg equation be calculated?

The Hardy-Weinberg equation used to determine genotype frequencies is: p 2 + 2pq + q 2 = 1. Where ‘p 2‘ represents the frequency of the homozygous dominant genotype (AA), ‘2pq‘ the frequency of the heterozygous genotype (Aa) and ‘q 2‘ the frequency of the homozygous recessive genotype (aa).

## What does Hardy Weinberg equation Mean?

The Hardy-Weinberg equation is a means by which the frequency of two alternate alleles can be predicted within a population.

What was the purpose of Hardy Weinberg’s work?

The primary purpose of Hardy Weinberg’s work was to calculate the allele and genotype frequency in a non evolving population (which does not experiences any evolutionary force).

What is Hardy Weinberg?

The Hardy-Weinberg principle was developed by the mathematician Godfrey Hardy and physician Wilhelm Weinberg in the early 1900’s. They constructed a model for predicting genotype and allele frequencies in a non-evolving population.
