## What does the Hardy-Weinberg equation tell us?

The Hardy-Weinberg equation is a mathematical equation that can be used **to calculate the genetic variation of a population at equilibrium**. … If the p and q allele frequencies are known, then the frequencies of the three genotypes may be calculated using the Hardy-Weinberg equation.

## Why do you think Hardy-Weinberg theory Cannot work in the natural world?

The HW equilibrium is used as a null hypothesis; genotypes occur in predicable frequencies and allele frequencies do not change over time. Hence, (generically) evolution is not occurring. … Actually, **the Hardy-Weinberg equilibrium cannot exist in real life**.

## How is the Hardy Weinberg theorem used as a null hypothesis for evolution?

How Is The Hardy Weinberg Theorem Used As A Null Hypothesis For Evolution? In evolution, **the Hardy-Weinberg Equilibrium can be applied as a null hypothesis to discover statistically significant deviations from the Equilibrium**. Based on certain assumptions, Hardy-Weinberg can be called a null hypothesis for evolution.

## 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.

## Which statement best describes the Hardy Weinberg principle?

Correct answer:

Explanation: By definition, the Hardy-Weinberg principle **states that genotype and allele frequencies will remain constant throughout generations**. In order for equilibrium to occur, there must be a large, randomly mating population with no selection, genetic drift, migration, or mutation.

## What is the purpose of Hardy-Weinberg equilibrium?

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**.

## Which statement is a reason that modern human populations never reach Hardy-Weinberg equilibrium?

Which statement is a reason that modern human populations never reach Hardy-Weinberg equilibrium? **Evolution rarely occurs in human populations.** **Mating is random in human populations.**
