# What are the components of the Hardy Weinberg equation?

Contents

The Hardy–Weinberg principle relies on a number of assumptions: (1) random mating (i.e, population structure is absent and matings occur in proportion to genotype frequencies), (2) the absence of natural selection, (3) a very large population size (i.e., genetic drift is negligible), (4) no gene flow or migration, (5) …

## What are the key components of the Hardy-Weinberg equilibrium?

Key points:

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 and what do the element represent?

The Hardy-Weinberg Equation

p = the frequency of the dominant allele in a population. q = the frequency of the recessive allele in a population. 2pq = the frequency of the heterozygous dominant genotype. p2 = the frequency of homozygous dominant genotype.

## What does the Hardy-Weinberg equation calculate?

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).

## What are the 5 assumptions of the Hardy-Weinberg principle?

The Hardy–Weinberg principle relies on a number of assumptions: (1) random mating (i.e, population structure is absent and matings occur in proportion to genotype frequencies), (2) the absence of natural selection, (3) a very large population size (i.e., genetic drift is negligible), (4) no gene flow or migration, (5) …

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

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

## What causes deviation from Hardy-Weinberg equilibrium?

Small Population Sizes: Genetic Drift

In a small population, the sampling of gametes and fertilization to create zygotes causes random error in allele frequencies. This results in a deviation from the Hardy-Weinberg Equilibrium. This deviation is larger at small sample sizes and smaller at large sample sizes.

## 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.

## How does Hardy-Weinberg calculate allele frequencies?

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.

## What does the Hardy-Weinberg principle predict?

The Hardy–Weinberg principle provides a mathematical model, which predicts that allele frequencies will not change from generation to generation. … where is the frequency of one (usually the dominant) allele and is the frequency of the other (usually recessive) allele of the gene.

## What is homozygous condition?

​Homozygous

Homozygous is a genetic condition where an individual inherits the same alleles for a particular gene from both parents.
