## What do p and q represent in Hardy-Weinberg?

The Hardy-Weinberg equation is a mathematical equation that can be used to calculate the genetic variation of a population at equilibrium. … where p is the frequency of the “A” allele and **q is the frequency of the “a” allele in the population**.

## What does the Q stand for in the Hardy-Weinberg equation?

M.Ed., Stanford University. 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 do PQ p2 2pq and q2 represent?

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 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**.

## How do you find q in Hardy-Weinberg?

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 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 question did Hardy and Weinberg want to answer?

Hardy and Weinberg wanted to answer the question; **how do allele and genotype frequencies change over generations**?
