## How do you know if something is 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.

## What are the 4 conditions of 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.

## What assumptions must be met for a population to be in Hardy-Weinberg equilibrium?

The five assumptions of Hardy-Weinberg equilibrium are a large population size, no natural selection, no mutation rate, no genetic drift, and random mating.

## How do you find the Hardy-Weinberg 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.

## What are the 5 principles of the Hardy-Weinberg equilibrium?

There are five basic Hardy-Weinberg assumptions: no mutation, random mating, no gene flow, infinite population size, and no selection.

## What does the Hardy-Weinberg model show?

The Hardy-Weinberg principle states that a population’s allele and genotype frequencies will remain constant in the absence of evolutionary mechanisms. Ultimately, the Hardy-Weinberg principle models a population without evolution under the following conditions: no mutations. no immigration/emigration.

## What are the factors affecting Hardy-Weinberg equilibrium?

– Five factors are known to influence the equilibrium of Hardy-Weinberg. These include gene migration or gene flow, genetic drift, mutation, genetic recombination and natural selection.

## Which of the following is not a requirement for Hardy-Weinberg equilibrium?

Answer: natural selection not a requirement for Hardy Weinberg equilibrium.

## Which condition is not among the requirements of Hardy-Weinberg equilibrium?

Hardy-Weinberg equilibrium requires no immigration or emigration, a large population, random mating, and no spontaneous mutations (all of which are virtually unavoidable in nature). Natural selection would violate these conditions.
