## What does the Hardy-Weinberg principle State quizlet?

what does the hardy-weinberg principle state? the Hardy-Weinberg principle states that allele frequencies in a population should remain constant unless one or more factors cause those frequencies to change.

Why is the Hardy Weinberg principle important?

The null hypothesis you are testing is that the observed and expected values are not significantly different from one another (because your expected values are calculated based on an assumption of Hardy-Weinberg equilibrium, this is the same as saying that the population is in H-W equilibrium for the genotype being …

### What are the conditions necessary for Hardy Weinberg equilibrium to occur quizlet?

Terms in this set (5) The population is very large. The population is isolated (no migration of individuals, or alleles, into or out of the population). 3. Mutations do not later the gene pool.

Why is the Hardy-Weinberg principle useful when studying population genetics?

By specifying the ideal conditions that must be met for allele frequencies to remain constant in populations, the H-W law can identify evolutionary forces that can cause changes in allele frequencies in the real world.

## How can the Hardy-Weinberg equation be calculated?

The Hardy-Weinberg equation used to determine genotype frequencies is: p 2 + 2pq + q 2 = 1. Where ‘p 2‘ represents the frequency of the homozygous dominant genotype (AA), ‘2pq‘ the frequency of the heterozygous genotype (Aa) and ‘q 2‘ the frequency of the homozygous recessive genotype (aa).

What is 2pq in the Hardy-Weinberg equation?

In the Hardy-Weinberg equation, “2pq” stands for the frequency of heterozygotes. [q] When using the Hardy-Weinberg equation to analyze a gene in a population’s gene pool, the observable quantity that will let you figure out everything else is…

### What is the Hardy Weinberg equation?

As such, evolution does happen in populations. Based on the idealized conditions, Hardy and Weinberg developed an equation for predicting genetic outcomes in a non-evolving population over time. This equation, p2 + 2pq + q2 = 1, is also known as the Hardy-Weinberg equilibrium equation.

What is Hardy Weinberg?

The Hardy-Weinberg principle was developed by the mathematician Godfrey Hardy and physician Wilhelm Weinberg in the early 1900’s. They constructed a model for predicting genotype and allele frequencies in a non-evolving population.
