What are two conditions that must be met for Hardy-Weinberg equilibrium to apply?

What are two conditions that must be met for Hardy-Weinberg equilibrium to apply?

The conditions to maintain the Hardy-Weinberg equilibrium are: no mutation, no gene flow, large population size, random mating, and no natural selection. The Hardy-Weinberg equilibrium can be disrupted by deviations from any of its five main underlying conditions.

Can Hardy-Weinberg equilibrium have mutations?

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.

Can Hardy Weinberg be used for multiple alleles?

Hardy Weinberg Calculations for Multiple Alleles at a Single Locus. For a gene locus segregating more than two alleles, the frequency of each allele is the frequency of its homozygote plus 1/2 the sum of the frequencies of all heterozygotes in which it can occur.

What are the factors affecting Hardy-Weinberg equilibrium?

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

What is one condition that must be met for a population to be genetic equilibrium?

The Hardy-Weinberg model states that a population will remain at genetic equilibrium as long as five conditions are met: (1) No change in the DNA sequence, (2) No migration, (3) A very large population size, (4) Random mating, and (5) No natural selection.

Which assumption must be met for a population to be in Hardy-Weinberg equilibrium for a specific gene?

The five assumptions of Hardy-Weinberg equilibrium are a large population size, no natural selection, no mutation rate, no genetic drift, and random mating.

Why is population 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.

What happens if the Hardy Weinberg equilibrium is violated?

Eggs and sperm collide at the same frequencies as the actual frequencies of p and q. When this assumption is violated and by chance some individuals contribute more alleles than others to the next generation, allele frequencies may change. This mechanism of allele change is called genetic drift.

Does random mating affect Hardy Weinberg equilibrium?

The Hardy-Weinberg Law states: In a large, random-mating population that is not affected by the evolutionary processes of mutation, migration, or selection, both the allele frequencies and the genotype frequencies are constant from generation to generation.
