## 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.
