# Frequent question: What is the Hardy Weinberg Principle What is a factor that can cause it not to occur?

Contents

The Hardy-Weinberg equilibrium can be disturbed by a number of forces, including mutations, natural selection, nonrandom mating, genetic drift, and gene flow. For instance, mutations disrupt the equilibrium of allele frequencies by introducing new alleles into a population.

## What are the factors affecting Hardy-Weinberg principle?

The 5 factors are – gene flow, mutation, genetic drift, genetic recombination and natural selection.

## What is the Hardy-Weinberg principle and what is it used for?

Hardy-Weinberg Equilibrium, also referred to as the Hardy-Weinberg principle, is used to compare allele frequencies in a given population over a period of time.

## What is the Hardy-Weinberg principle simple?

In population genetics, the Hardy–Weinberg principle, also known as the Hardy–Weinberg equilibrium, model, theorem, or law, states that allele and genotype frequencies in a population will remain constant from generation to generation in the absence of other evolutionary influences.

## What is the Hardy-Weinberg principle quizlet?

Hardy-Weinberg Principle states. principle that allele and genotype frequencies in a population will remain constant unless one or more factors cause the frequencies to change. Hardy-Weinberg formula. p² + 2pq + q² = 1 ; can be used to determine if a populations is in genetic equilibrium.

## What is the major factors causing deviation from the Hardy-Weinberg equilibrium?

The Hardy-Weinberg equilibrium can be disrupted by deviations from any of its five main underlying conditions. Therefore mutation, gene flow, small population, nonrandom mating, and natural selection will disrupt the equilibrium.

## What are the factors that affect allele frequency and how they are affected?

Five factors are known to affect allele frequency in populations i.e., Hardy-Weinberg equilibrium. These are gene migration or gene flow, genetic drift, mutation, genetic recombination and natural selection. Gene migration or gene flow – it is movement of alleles into a gene pool or out of a gene pool.

## What do the variables in the Hardy-Weinberg equation represent?

In the Hardy-Weinberg equations, what quantities are represented by the variables and ? Explanation: The variables and are specifically referring to the allele frequencies of the dominant and the recessive allele in a population, respectively.

## How does Hardy-Weinberg calculate allele frequency?

The Hardy-Weinberg equation used to determine genotype frequencies is: p2 + 2pq + q2 = 1. Where ‘p2‘ represents the frequency of the homozygous dominant genotype (AA), ‘2pq’ the frequency of the heterozygous genotype (Aa) and ‘q2‘ the frequency of the homozygous recessive genotype (aa).

## Which of the following is a violation of the Hardy Weinberg equilibrium?

One of the violations of Hardy-Weinberg equilibrium is selective mating. If birds prefer to mate with others that are similarly colored, then Hardy-Weinberg equilibrium is violated and the gene pool in the population is changing.

## What idea did Hardy and Weinberg disprove?

They disproved the idea that dominant alleles’ percentages will rise throughout generations, which causes recessive alleles’ percentages to sink.

## What are the five factors that can lead to evolution?

Five different forces have influenced human evolution: natural selection, random genetic drift, mutation, population mating structure, and culture.

## What does the Hardy-Weinberg equilibrium measure?

The equation is an expression of the principle known as Hardy-Weinberg equilibrium, which states that the amount of genetic variation in a population will remain constant from one generation to the next in the absence of disturbing factors.

## What is the Hardy-Weinberg symbol for the frequency of the dominant allele 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.
