There are five basic Hardy-Weinberg assumptions: no mutation, random mating, no gene flow, infinite population size, and no selection. If the assumptions are not met for a gene, the population may evolve for that gene (the gene’s allele frequencies may change).

## What are the conditions necessary for Hardy-Weinberg equilibrium to occur?

Hardy-Weinberg equilibrium has a set of conditions that must be met in order for the population to have unchanging gene pool frequencies. There **must be random mating, no mutation, no migration**, no natural selection, and a large sample size. It is not necessary for the population to be at carrying capacity.

## Why is random mating necessary for Hardy-Weinberg equilibrium?

If allele frequencies differ between the sexes, it takes two generations of **random mating** to attain **Hardy**–**Weinberg equilibrium**. Sex-linked loci require multiple generations to attain **equilibrium** because one sex has two copies of the gene and the other sex has only one.

## 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**.

## How do you know if it’s in 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.

## Does inbreeding violate Hardy-Weinberg?

Inbreeding – How does it affect a population? In a small population, the sampling of gametes and fertilization to create zygotes causes **random error** in allele frequencies. This results in a deviation from the Hardy-Weinberg Equilibrium. This deviation is larger at small sample sizes and smaller at large sample sizes.

## What are the two equations for Hardy-Weinberg equilibrium What does each variable represent?

The frequency of genotypes in a population can be represented by **p ^{2}+2pq+q^{2}= 1**, with p

^{2}equal to the frequency of the homozygous dominant genotype, 2pq equal to the frequency of the heterozygous genotype, and q

^{2}equal to the frequency of the recessive genotype.

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

Genetic equilibrium is a condition **where a gene pool is not changing in frequency across generations**. This is because the evolutionary forces acting upon the allele are equal. As a result, the population does not evolve even after several generations.

## Which of the following is not required for a population to be in Hardy-Weinberg equilibrium?

Hardy-Weinberg equilibrium has a set of conditions that must be met in order for the population to have unchanging gene pool frequencies. There must be **random mating**, no mutation, no migration, no natural selection, and a large sample size. It is not necessary for the population to be at carrying capacity.

## What does P mean 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.
