## What is a requirement for a population to be in Hardy-Weinberg equilibrium?

When a population is in Hardy-Weinberg equilibrium for a gene, **it is not evolving**, and allele frequencies will stay the same across generations. There are five basic Hardy-Weinberg assumptions: no mutation, random mating, no gene flow, infinite population size, and no selection.

## Which population is not in Hardy-Weinberg equilibrium?

If **the allele frequencies after one round of random mating change at all from the original frequencies**, the population is not in Hardy-Weinberg equilibrium and evolution has occurred within the population.

## What are the 4 conditions of Hardy-Weinberg equilibrium?

The Hardy-Weinberg model states that a population will remain at genetic equilibrium as long as five conditions are met: (1) No change in the DNA sequence, (2) No migration, (3) A very large population size, **(4) Random mating, and (5) No natural selection**.

## Which of the following is not a condition of Hardy-Weinberg?

Which of the following is NOT a condition of the Hardy-Weinberg equilibrium? **Mutations cannot occur in a population**.

## Which does not affect Hardy-Weinberg equilibrium?

The Hardy-Weinberg Law states: In a large, random-mating population that is not affected by the **evolutionary processes of mutation**, migration, or selection, both the allele frequencies and the genotype frequencies are constant from generation to generation. …

## What happens in a population that is not in Hardy-Weinberg equilibrium quizlet?

A population in Hardy-Weinberg equilibrium **is not evolving**. If any of these conditions are violated, the population does not stay in Hardy-Weinberg equilibrium, and allele frequencies and genotype frequencies may change from one generation to the next.

## When a population is in Hardy-Weinberg equilibrium quizlet?

Hardy-Weinberg equilibrium: the condition **in which both allele and genotype frequencies in a population remain constant from generation to generation unless** specific disturbances occur.

## Why does Hardy-Weinberg need large population?

Large Population

A population must **be large enough that chance occurrences cannot significantly change allelic frequencies significantly**. … Large populations are unlikely to be affected by chance changes in allele frequencies because those chance changes are very small in relation to the total number of allele copies.

## How do you know if a population 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.
