## When the conditions of the Hardy-Weinberg equilibrium are met?

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 happens 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**. -A population in Hardy-Weinburg equilibrium is not changing genetically, not evolving.

## Which of the following is not a condition that must be met for 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.

## What is the purpose 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**.

## What is the purpose of calculating Hardy-Weinberg equilibrium?

In population genetics studies, the **Hardy**–**Weinberg equation** can be used to measure whether the observed genotype frequencies in a population differ from the frequencies predicted by the **equation**.

## Why is there a 2 in 2pq?

The term p2 represents **the frequency of dominant homozygotes (AA)** and the term q2 represents the frequency of recessive homozygotes (aa). p represents the allele frequency of allele A, and q represents the allele frequency of the allele a.

## How do you test for Hardy-Weinberg equilibrium?

We can check if a population is in genetic equilibrium by testing if the Hardy-Weinberg principle applies, as follows: Given the population genotype numbers, (1) **calculate the allele frequencies from the observed population genotype numbers**. (2) calculate the genotype frequencies from the observed genotype numbers.

## What 5 conditions are required for a population to stay in 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 is a characteristic of a population at Hardy-Weinberg equilibrium quizlet?

They are said to be in Hardy-Weinberg equilibrium: – Very large population: **No genetic drift can occur**. -No immigration or immigration: No gene flow can occur. -No mutations: No new alleles can be added to the gene pool.
