## What are the factors that affect Hardy Weinberg equilibrium?

Five conditions are required in order for a population to remain at Hardy-Weinberg equilibrium:A large breeding population.Random mating.No change in allelic frequency due to mutation.No immigration or emigration.No natural selection..

## Why is there a 2 in 2pq?

where p is the frequency of the “A” allele and q is the frequency of the “a” allele in the population. In the equation, p2 represents the frequency of the homozygous genotype AA, q2 represents the frequency of the homozygous genotype aa, and 2pq represents the frequency of the heterozygous genotype Aa.

## What does it mean if a population is in 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. … For instance, mutations disrupt the equilibrium of allele frequencies by introducing new alleles into a population.

## What does it mean if a population is in genetic equilibrium?

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 are five conditions that can disrupt genetic equilibrium?

The Hardy-Weinberg equilibrium can be disrupted by deviations from any of its five main underlying conditions. Therefore mutation, gene flow, small population, nonrandom mating, and natural selection will disrupt the equilibrium.

## How can Hardy Weinberg equilibrium be affected explain giving three reasons?

Factors which affect Hardy-Weinberg equilibrium are: (i)Gene migration or gene flow Due to migration, new genes or alleles are added to the new population and these are lost from the old population, in turn, changing the frequencies….Gene migration.Genetic drift.Mutation and recombination.Natural selection.

## 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.

## Why is Hardy Weinberg equilibrium unlikely?

If any one of these assumptions is not met, the population will not be in Hardy-Weinberg equilibrium. Instead, it may evolve: allele frequencies may change from one generation to the next. Allele and genotype frequencies within a single generation may also fail to satisfy the Hardy-Weinberg equation.

## What do p2 2pq and q2 represent?

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.

## Why is random mating important to Hardy Weinberg?

Random mating. The HWP states the population will have the given genotypic frequencies (called Hardy–Weinberg proportions) after a single generation of random mating within the population. … A common cause of non-random mating is inbreeding, which causes an increase in homozygosity for all genes.

## Why is Hardy Weinberg equilibrium important?

Importance: The Hardy-Weinberg model enables us to compare a population’s actual genetic structure over time with the genetic structure we would expect if the population were in Hardy-Weinberg equilibrium (i.e., not evolving).

## Are humans in Hardy Weinberg equilibrium?

12.3. When a population meets all the Hardy-Weinberg conditions, it is said to be in Hardy-Weinberg equilibrium (HWE). Human populations do not meet all the conditions of HWE exactly, and their allele frequencies will change from one generation to the next, so the population evolves.

## What does P and Q stand for in the Hardy Weinberg equation?

To estimate the frequency of alleles in a population, we can use the Hardy-Weinberg equation. According to this equation: p = the frequency of the dominant allele (represented here by A) q = the frequency of the recessive allele (represented here by a)
