## What is the Hardy-Weinberg equilibrium used to describe 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**.

## How do you know if Hardy-Weinberg is in 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?

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 are conditions for Hardy-Weinberg equilibrium quizlet?

The conditions to maintain the Hardy-Weinberg equilibrium are: **no mutation, no gene flow, large population size, random mating, and no natural selection**. The Hardy-Weinberg equilibrium can be disrupted by deviations from any of its five main underlying conditions.

## 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 assumptions of Hardy-Weinberg equilibrium quizlet?

The Hardy-Weinberg model makes the following assumptions: **no selection at the gene in question; no genetic drift; no gene flow**; no mutation; random mating.

## What are the five assumptions that the Hardy-Weinberg formula uses to calculate traits within a population?

A low rate of mutations would help keep a population in 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.

## How do you find the equilibrium frequency?

Now solve for p and convince yourself that the equilibrium frequency **= p = v/(u+v)**. Similarly the equilibrium frequency of q = u/(u+v).
