## What is the Hardy-Weinberg model used for?

Importance: The Hardy-Weinberg model enables **us to compare a population’s actual genetic structure over time with the genetic structure** we would expect if the population were in Hardy-Weinberg equilibrium (i.e., not evolving).

## What is the Hardy-Weinberg equation and what does it predict?

The Hardy-Weinberg equation allows us to predict which ones they are. … Knowing p and q, it is a simple matter to plug these values into the Hardy-Weinberg equation **(p² + 2pq + q² = 1)**. This then provides the predicted frequencies of all three genotypes for the selected trait within the population.

## Why is the Hardy-Weinberg principle important?

This relationship, known as the Hardy-Weinberg principle, is important **because we can use it to determine if a population is in equilibrium for a particular gene**. The Hardy-Weinberg principle applies to individual genes with two alleles, a dominant allele and a recessive allele.

## Why is the Hardy-Weinberg model useful quizlet?

Why is the Hardy-Weinberg principle useful? The Hardy-Weinberg principle represents **an ideal situation that seldom occurs in the natural world**. In unrestricted random mating, each individual in a population has an equal chance of mating with any individual of the opposite sex.

## What are the predictions given by the Hardy Weinberg law?

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**.

## What is the Hardy-Weinberg equation quizlet?

Candidates should be able to calculate allele, genotype and phenotype frequencies from appropriate data and from the Hardy-Weinberg equation, **p2 + 2pq + q2 = 1** where p is the frequency of the dominant allele and q is the frequency of the recessive allele.

## What do you understand by Hardy Weinberg law?

Hardy-Weinberg law, **an algebraic equation that describes the genetic equilibrium within a population**. … Individual variations occur because of the various genetic combinations that result from random mating of individuals, but nonrandom, or selective, mating must occur for natural selection to take place.

## What is the Hardy-Weinberg equation and when is it used quizlet?

The Hardy-Weinberg equation can be used to: **-Determine probable frequencies of genotypes in a population**. -Track changes of genotypes from generation to generation. Genotype frequency: the percentage of a specific genotype within a population.
