# If the hardy-weinberg equilibrium is met, what is the net effect?

## What affects the Hardy Weinberg equilibrium the most?

Some of the major factors which affect the genetic equilibrium and induce the variability in population are as follows: (A) Mutations (B) Recombinations during Sexual Reproduction (C) Genetic Drift (D) Gene Migration (Gene Flow) (E) Natural Selection.

## What does the Hardy Weinberg equilibrium illustrate?

The Hardy – Weinberg equilibrium principle describes the unchanging frequency of alleles and genotypes in a stable, idealized population. In the absence of these evolutionary forces, the population would reach an equilibrium in one generation and maintain that equilibrium over successive generations.

## How does the Hardy Weinberg equation work?

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.

## How can Hardy Weinberg equilibrium be affected explain giving three reasons?

Answer: some of the major factors which affect the genetic equilibrium and induce the variability in population are as follows: (A) Mutations (B) Recombinations during Sexual Reproduction (C) Genetic Drift (D) Gene Migration (Gene Flow) (E) Natural Selection. ADVERTISEMENTS: (iii) Most mutations are harmful or neutral.

## How do you know if it’s in Hardy Weinberg equilibrium?

To know if a population is in Hardy – Weinberg Equilibrium scientists have to observe at least two generations. If the allele frequencies are the same for both generations then the population is in Hardy – Weinberg Equilibrium.

## Which does not affect Hardy Weinberg equilibrium?

Hardy – Weinberg equilibrium is known to be affected by gene flow, genetic drift, mutation, genetic recombination and.

## Does inbreeding violate Hardy Weinberg?

The Hardy Weinberg equilibrium holds good in a population if the mutation is absent and population structure is absent (random mating), also the population must be large enough. Inbreeding is not random mating, hence it does not change the gene frequency.

## Are humans in Hardy Weinberg equilibrium?

12.3. When a population meets all the Hardy – Weinberg conditions, it is said to be in Hardy – Weinberg equilibrium (HWE). Human populations do not meet all the conditions of HWE exactly, and their allele frequencies will change from one generation to the next, so the population evolves.

## What happens when a population is in Hardy Weinberg equilibrium?

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 does the 2 mean in 2pq?

In the equation, p 2 represents the frequency of the homozygous genotype AA, q 2 represents the frequency of the homozygous genotype aa, and 2pq represents the frequency of the heterozygous genotype Aa.

## How do you solve Hardy Weinberg Problems?

Step 1: Assign the Alleles. • By convention, we use the dominant phenotype to name the alleles. Step 2: Calculate q. The number of homozygous recessive individuals is q. Step 3: Calculate p. Once you have q, finding p is easy! Step 4: Use p and q to calculate the remaining genotypes. I always suggest that you calculate q.

## Why is the Hardy Weinberg equilibrium useful?

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 are the factors that affect genetic equilibrium?

-The factors that affect the genetic equilibrium and induce the variability in the population are as follows: mutations, recombinations during sexual reproduction, genetic drift, gene migration or gene flow, and natural selection.

## Does random mating affect Hardy Weinberg equilibrium?

It is important to recognize that the Hardy – Weinberg equilibrium is a neutral equilibrium, which means that a population perturbed from its Hardy – Weinberg genotype frequencies will indeed reach equilibrium after a single generation of random mating (if it conforms to the other assumptions of the theorem), but it will

## How does genetic drift affect Hardy Weinberg equilibrium?

But in the Hardy – Weinberg equilibrium, the population is infinite, there’s an infinity of individuals, so the genetic drift doesn’t occure. So the genetic drift don’t affect the Hardy – Weinberg equilibrium.
