What is a prediction of the Hardy-Weinberg law if the assumptions about the population is correct? The population’s allelic frequencies stabilize.

## What are the predictions given by the Hardy-Weinberg law?

There are five basic Hardy-Weinberg assumptions: **no mutation, random mating, no gene flow, infinite population size, and no selection**. If the assumptions are not met for a gene, the population may evolve for that gene (the gene’s allele frequencies may change).

## What happens when any of the Hardy-Weinberg assumptions is no longer held for a population?

If a population violates one of the following four assumptions, the population may continue to have Hardy–Weinberg proportions each generation, but **the allele frequencies will change over time**. Selection, in general, causes allele frequencies to change, often quite rapidly.

## What is a possible explanation for why a population may not be in Hardy-Weinberg equilibrium?

What is a possible explanation for why a population may not be in Hardy-Weinberg equilibrium? **Evolution is occurring on a trait in the population**. When we say “populations evolve, not individuals,” what does this mean? Individuals cannot change their genetic makeup, but genotype frequencies in a population can change.

## 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**.

## What would violate the conditions of Hardy-Weinberg equilibrium?

If a population is in Hardy-Weinberg equilibrium, there is no evolution taking place in the population. One of the violations of Hardy-Weinberg equilibrium is **selective mating**. … Hardy-Weinberg requires no migration, random mating, large population size, no natural selection, and no mutation.

## 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.

## 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.

## How do you know if something is 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.

## What can be said about a population in Hardy-Weinberg equilibrium?

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.

## Which is most likely to occur in a population in Hardy-Weinberg equilibrium?

The answer to your question is, **Random mating**.
