What is the Hardy Weinberg equilibrium and under what conditions is it upheld?

Explanation: Hardy-Weinberg equilibrium has a set of conditions that must be met in order for the population to have unchanging gene pool frequencies. There must be random mating, no mutation, no migration, no natural selection, and a large sample size. It is not necessary for the population to be at carrying capacity.

What are the 5 conditions that must occur to reach Hardy-Weinberg equilibrium?

There are five basic HardyWeinberg assumptions: no mutation, random mating, no gene flow, infinite population size, and no selection.

What is the Hardy-Weinberg law of equilibrium and what can it tell us?

The Hardy-Weinberg equilibrium is a principle stating that the genetic variation in a population will remain constant from one generation to the next in the absence of disturbing factors. … For instance, mutations disrupt the equilibrium of allele frequencies by introducing new alleles into a population.

What is Hardy-Weinberg equilibrium used for?

Hardy-Weinberg Equilibrium (HWE) is used to estimate the number of homozygous and heterozygous variant carriers based on its allele frequency in populations that are not evolving.

What does it mean if a population is not in Hardy-Weinberg equilibrium?

If the allele frequencies after one round of random mating change at all from the original frequencies, the population is not in Hardy-Weinberg equilibrium and evolution has occurred within the population.

Which factor does not affect Hardy-Weinberg equilibrium?

According to the Hardy Weinberg law, the allele and genotype frequencies in a population remain constant under absence of factors responsible for evolution. These factors are namely mutation, recombination, gene migration, genetic drift and natural selection.

Why is random mating important to Hardy-Weinberg?

If allele frequencies differ between the sexes, it takes two generations of random mating to attain Hardy-Weinberg equilibrium. Sex-linked loci require multiple generations to attain equilibrium because one sex has two copies of the gene and the other sex has only one.

Does inbreeding violate Hardy-Weinberg?

Inbreeding – How does it affect a population? 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 does it mean if a population is in genetic equilibrium?

Genetic equilibrium is a condition where a gene pool is not changing in frequency across generations. This is because the evolutionary forces acting upon the allele are equal. As a result, the population does not evolve even after several generations.
