When a population is in Hardy-Weinberg equilibrium for a gene, it is not evolving, and allele frequencies will stay the same across generations. … They are: mutation, non-random mating, gene flow, finite population size (genetic drift), and natural selection.

## Do allele frequencies change over time in Hardy-Weinberg equilibrium?

allele frequencies in a **population will not change from generation to generation**. … This frequency distribution will not change from generation to generation once a population is in Hardy-Weinberg equilibrium.

## What happens to allele frequency?

The allele frequency represents **the incidence of a gene variant in a population**. … Changes in allele frequencies over time can indicate that genetic drift is occurring or that new mutations have been introduced into the population.

## How does Hardy-Weinberg calculate allele frequency?

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.

## Do genotype frequencies change in Hardy-Weinberg equilibrium?

The Hardy-Weinberg equilibrium can be disturbed by a number of forces, including mutations, natural selection, nonrandom mating, genetic drift, and gene flow. For instance, mutations **disrupt** the equilibrium of allele frequencies by introducing new alleles into a population.

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

The answer is the frequency of the recessive allele **will increase**.

## Which factor does not affect Hardy-Weinberg equilibrium?

According to the Hardy Weinberg law, the allele and genotype frequencies in a population remain constant under absence of factors responsible for evolution. These factors are namely **mutation, recombination, gene migration, genetic drift and natural selection**.

## How do you find the percentage of allele frequencies?

Answer: The frequency of the dominant (normal) allele in the population (p) is simply **1 – 0.02 =** 0.98 (or 98%). The percentage of heterozygous individuals (carriers) in the population. Answer: Since 2pq equals the frequency of heterozygotes or carriers, then the equation will be as follows: 2pq = (2)(.

## What is P and Q in Hardy-Weinberg?

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**.
