# What do each variables in the Hardy Weinberg equation represent?

Contents

Hardy-Weinberg Equations and Analysis. According to the Hardy-Weinberg principle, the variable p often represents the frequency of a particular allele, usually a dominant one. … The variable q represents the frequency of the recessive allele, y, for green pea pods.

## What do variables in the Hardy-Weinberg equation represent?

In the Hardy-Weinberg equations, what quantities are represented by the variables and ? Explanation: The variables and are specifically referring to the allele frequencies of the dominant and the recessive allele in a population, respectively.

## What is P and Q in the Hardy-Weinberg equation?

The Hardy-Weinberg Law is an equation for calculating the frequencies of different alleles and genotypes in a population in genetic equilibrium and expressed by the formula p + q = 1 where p is the frequency of the dominant allele and q is the frequency of the recessive allele.

## What are the 5 parts of the Hardy Weinberg principle?

The Hardy–Weinberg principle relies on a number of assumptions: (1) random mating (i.e, population structure is absent and matings occur in proportion to genotype frequencies), (2) the absence of natural selection, (3) a very large population size (i.e., genetic drift is negligible), (4) no gene flow or migration, (5) …

## What variable represents the heterozygous trait?

Individuals with genotypes AA and aa are homozygotes (i.e., they have two copies of the same allele). Individuals with genotype Aa are heterozygotes (i.e., they have two different alleles at the A locus).

## Which of the following does the variable 2pq represent?

Explanation: In the Hardy-Weinberg equilibrium equation ( p2+2pq+q2=1 ), the term 2pq represents the genotype frequency of heterozygotes (Aa) in a population in equilibrium. The term p2 represents the frequency of dominant homozygotes (AA) and the term q2 represents the frequency of recessive homozygotes (aa).

## What does the Q represent in the Hardy-Weinberg equation quizlet?

According to the Hardy-Weinberg equation, what does ‘q’ represent? Frequency of the recessive allele.

## What are the 5 conditions that must be present in order for the Hardy-Weinberg principles to make accurate predictions which of these conditions are never truly met?

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.

## How do I find 2pq?

The percentage of heterozygous individuals (carriers) in the population. Answer: Since 2pq equals the frequency of heterozygotes or carriers, then the equation will be as follows: 2pq = (2)(. 98)(.

## What are the 5 evolutionary mechanisms?

There are five key mechanisms that cause a population, a group of interacting organisms of a single species, to exhibit a change in allele frequency from one generation to the next. These are evolution by: mutation, genetic drift, gene flow, non-random mating, and natural selection (previously discussed here).

## What variable remains constant or in equilibrium in the Hardy-Weinberg model?

The Hardy-Weinberg principle states that a population’s allele and genotype frequencies will remain constant in the absence of evolutionary mechanisms.

## What are the five parameters that allow this equilibrium equation to work?

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.

## What is Hardy Weinberg symbol for the frequency of the dominant allele?

² is the frequency of individuals with the homozygous dominant genotype.

## 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.
