## What are the 5 principles of the Hardy Weinberg equilibrium?

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 is P and Q in Hardy Weinberg?

This has become known as the Hardy-Weinberg equilibrium equation. In this equation (p² + 2pq + q² = 1), p is defined as the frequency of the dominant allele and q as the frequency of the recessive allele for a trait controlled by a pair of alleles (A and a).

## How do you calculate P and Q?

To find q, simply take the square root of 0.09 to get 0.3. Since p = 1 – 0.3, then p must equal 0.7. 2pq = 2 (0.7 x 0.3) = 0.42 = 42% of the population are heterozygotes (carriers).

## How do you find the equilibrium frequency?

Now solve for p and convince yourself that the equilibrium frequency = p = v/(u+v). Similarly the equilibrium frequency of q = u/(u+v). In the real world we will generally not find specific evolutionary forces acting alone; there will always be some other force that might counteract a specific force of interest.

## Why is there a 2 in 2pq?

In the equation, p2 represents the frequency of the homozygous genotype AA, q2 represents the frequency of the homozygous genotype aa, and 2pq represents the frequency of the heterozygous genotype Aa.

## Does inbreeding violate Hardy Weinberg?

There is an equation used to predict the frequency of alleles in Hardy-Weinberg populations. That equation is called the Hardy-Weinberg equation. When inbreeding occurs, the amount of heterozygotes will decrease because the individuals that are mating have the same alleles.

## What are the two Hardy Weinberg equations?

For a population in genetic equilibrium: p + q = 1.0 (The sum of the frequencies of both alleles is 100%.) This page contains all the information you need to calculate allelic frequencies when there are two different alleles.

## What is Q 2 Hardy Weinberg?

When Hardy-Weinberg equilibrium is met the following equation is true: p2 +2pq + q2 = 1. Where p2 represents the frequency of the homozygous dominant genotype, q2 represents the frequency of the recessive genotype and 2pq is the frequency of the heterozygous genotype.

## What is Hardy Weinberg equilibrium used for?

Hardy-Weinberg Equilibrium, also referred to as the Hardy-Weinberg principle, is used to compare allele frequencies in a given population over a period of time.

## What does the Hardy Weinberg principle predict?

The Hardy-Weinberg principle predicts that allelic frequencies remain constant from one generation to the next, or remain in EQUILIBRIUM, if we assume certain conditions (which we will discuss below). No migration – so no alleles enter or leave the population. No mutation – so allelic characteristics do not change.

#### H2o2 decomposition equation

What does h2o2 decompose into? Hydrogen peroxide can easily break down, or decompose, into water and oxygen by breaking up into two very reactive parts – either 2OHs or an H and HO2: If there are no other molecules to react with, the parts will form water and oxygen gas as these are more stable […]
