# Question: What does P mean in Hardy Weinberg?

Contents

## How do you find P 2 in Hardy-Weinberg?

Since p = 1 – q then 1 – 0.59 = 0.41. Now that we know the frequency of each allele, we can calculate the frequency of the remaining genotypes in the population (AA and Aa individuals). AA = p2 = 0.41 x 0.41 = 0.17; Aa = 2pq = 2 (0.59) (0.41) = 0.48; and as before aa = q2 = 0.59 x 0.59 = 0.35.

## How do you calculate P and Q?

We can calculate the values of p and q, in a representative sample of individuals from a population, by simply counting the alleles and dividing by the total number of alleles examined. For a given allele, homozygotes will count for twice as much as heterozygotes.

## What is p2 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.

## What is meant by an allele?

An allele is a variant form of a gene. Some genes have a variety of different forms, which are located at the same position, or genetic locus, on a chromosome. … Genotypes are described as homozygous if there are two identical alleles at a particular locus and as heterozygous if the two alleles differ.

## What is meant by genetic load?

Genetic load is a number between 0 and 1 and it measures the extent to which the average individual in a population is inferior to the best possible kind of individual. The genetic load equals the relative chance that an average individual will die before reproducing because of the deleterious genes that it possesses.

## What are the frequencies of the P and Q alleles in the final population?

allele frequencies in a population will not change from generation to generation. if the allele frequencies in a population with two alleles at a locus are p and q, then the expected genotype frequencies are p2, 2pq, and q2.

## What does the Hardy-Weinberg equation predict for the new P and Q?

Hardy-Weinberg believed that evolution occurs because the frequency of alleles changes. … The p’s represent the frequency of the A allele and the q represents the frequency of the a allele in a diploid individual. Hardy-Weinberg equilibrium is p2+2pq+q2=1.

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

There are five basic Hardy-Weinberg assumptions: no mutation, random mating, no gene flow, infinite population size, and no selection.
