# Quick Answer: What does the allele frequency have to total in the Hardy Weinberg equilibrium?

Contents

## How does Hardy-Weinberg calculate allele frequencies?

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 is the main point of Hardy-Weinberg equilibrium?

The Hardy-Weinberg equilibrium is a principle stating that the genetic variation in a population will remain constant from one generation to the next in the absence of disturbing factors.

## What is equilibrium allele frequency?

This is useful because it lets us calculate a theoretical equilibrium frequency which is defined as the point at which there is no more change in allele frequencies, i.e. when Dp = 0 which is when (pt+1) = (pt); from above: pt(1-u) + (1-p)t(v) = pt [remember, q=(1-p)].

## 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.

## How do you calculate phenotype frequency?

To compare different phenotype frequencies, the relative phenotype frequency for each phenotype can be calculated by counting the number of times a particular phenotype appears in a population and dividing it by the total number of individuals in the population.

## What is meant by an allele?

An allele is a variant form of a gene. Some genes have a variety of different forms, which are located at the same position, or genetic locus, on a chromosome. … Genotypes are described as homozygous if there are two identical alleles at a particular locus and as heterozygous if the two alleles differ.

## What will happen to the frequency of the recessive allele?

The frequency will remain the same. Homozygous recessive individuals selectively leaving a population is an example of: … What will happen to the frequency of the recessive allele for the HbS gene when there is an outbreak of malaria? The frequency will increase.
