## What do P and Q stand for in the Hardy-Weinberg equation quizlet?

STUDY. What does p stand for in the Hardy-Weinberg equation? The dominant allele. What does q stand for in the Hardy-Weinberg equation? The recessive allele.

## What do the letters P and Q represent in Hardy-Weinberg?

The Hardy-Weinberg Equation

p = the frequency of the dominant allele in a population. q = the frequency of the recessive allele in a population.

## 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 does the variable Q represent?

Mathematics usually uses letters from the end of the alphabet to represent variables. Economics however often uses the first letter of the item which varies to represent variables. Thus p is used for the variable price and q is used for the variable quantity.

## Which allele is represented by the Q variable in the Hardy-Weinberg equation?

p represents the allele frequency of allele A, and q represents the allele frequency of the allele a.

## 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 do p and q represent?

The p represents the frequency of the dominant allele. The q represents the frequency of the recessive allele.

## When speaking in terms of Hardy-Weinberg equilibrium What does the variable Q represent?

The variable q represents the frequency of the recessive allele, y, for green pea pods. If p and q are the only two possible alleles for this characteristic, then the sum of the frequencies must add up to 1, or 100 percent. We can also write this as p + q = 1.

## What does P and Q represent in science?

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.
