We solve this for q to give the equilibrium allele frequency , q-hat: q = sqrt(u/s) (sqrt stands for square root). Most mutation rates are fairly small numbers (about 10-6), so this equation suggests that deleterious alleles will be maintained in mutation selection balance at fairly low frequencies.

## What is the equation for allele frequency?

1 = p^{2} + 2pq + q^{2}

P and q each represent the allele frequency of different alleles. The term p^{2} represents the frequency of the homozygous dominant genotype. The other term, q^{2}, represents the frequency of the homozygous recessive genotype.

## How do you calculate Hardy Weinberg equilibrium?

To know if a population is in Hardy-Weinberg Equilibrium scientists have to observe at least two generations. If the allele frequencies are the same for both generations then the population is in Hardy-Weinberg Equilibrium.

## What do you mean by equilibrium of gene frequency?

Genetic equilibrium is the condition of an allele or genotype in a gene pool (such as a population) where the frequency does not change from generation to generation.

## What is the difference between genotype frequency and allele frequency?

Definition. Genotype frequency refers to the number of individuals with a given genotype divided by the total number of individuals in the population while allele frequency refers to the frequency of occurrence or proportions of different alleles of a particular gene in a given population.

## How do you find the frequency of an allele in next generation?

The frequency of A alleles is p^{2} + pq, which equals p^{2} + p (1 — p) = p^{2} + p — p^{2} = p ; that is, p stays the same from one generation to the next.

…

- The frequency of AA individual will be p
^{2}. - The frequency of Aa individuals will be 2pq.
- The frequency of aa individuals will be q
^{2}.

## What are allele frequencies quizlet?

Allele frequency. Number of times an allele occurs in a gene pool compared with the number of alleles in that pool for the same gene. Polygenic trait. Trait controlled by two or more genes.

## How do you find Hardy Weinberg genotype frequencies?

Count up the aa types and you have the observed q^{2}. Then, take the square root of q^{2} to get q, and then subtract q from 1 to get p. Square p to get p^{2} and multiply 2*p*q to get the observed heterozygous Aa genotype frequency.
