## 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 = p^{2} = 0.41 x **0.41** = 0.17; Aa = 2pq = 2 (0.59) (0.41) = 0.48; and as before aa = q^{2} = 0.59 x 0.59 = 0.35.

## What does P represent in Hardy Weinberg?

In order to express Hardy Weinberg principle mathematically , suppose “p” represents **the frequency of the dominant allele in gene pool** and “q” represents the frequency of recessive allele. p+q=1 since the sum of both frequencies is 100% .

## Why is there a 2 in 2pq but not in p2 or q2?

9. Why is there a “2” in “2pq” but not in “p2” nor “q2”? **16% of a population is unable to taste the chemical PTC**. These non- tasters are recessive for the tasting gene.

## Why is the 2 in the term 2pq necessary?

Transcribed image text: In the formula for determining a population’s genotype frequencies, the pq in the term 2pq is necessary **because the population is diploid**. heterozygotes can come about in two ways. the population is doubling in number. heterozygotes have two alleles.

## What is p2 2pq q2?

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.

## 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 P 2 represent in the equation apex?

The term p2 represents **the frequency of dominant homozygotes (AA)** and the term q2 represents the frequency of recessive homozygotes (aa). p represents the allele frequency of allele A, and q represents the allele frequency of the allele a.

## What does P represent in the Hardy Weinberg principle quizlet?

P= **Dominant allele/total amount**. **Only $47.88/year**. How would you find the freq of the q (recessive) allele. Q= Recessive allele/total amount. What is the hardy weinberg equation?

## How do you calculate p value in Hardy-Weinberg?

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.
