# What does 2pq equal?

## What does 2pq equal?

Answer: The frequency of heterozygous individuals is equal to 2pq. In this case, 2pq equals 0.32, which means that the frequency of individuals heterozygous for this gene is equal to 32% (i.e. 2 (0.8)(0.2) = 0.32).

## What does 2pq mean in Hardy Weinberg?

2pq in Hardy Weinberg equation represents percentage of heterozygous individuals in a population.

What is the equation for allele frequency?

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.

### 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.

### What does the 2 stand for in 2pq?

Explanation: In the Hardy-Weinberg equilibrium equation ( p2+2pq+q2=1 ), the term 2pq represents the genotype frequency of heterozygotes (Aa) in a population in equilibrium. The term p2 represents the frequency of dominant homozygotes (AA) and the term q2 represents the frequency of recessive homozygotes (aa).

Why is the 2 necessary in 2pq?

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.

#### Why is 2pq not PQ?

Note that the heterozygotes are not 2pq but pq because in each case they are only being considered for the one allele in question. If we scale all wii’s such that the largest = 1.0 we refer to these as the relative fitnesses of the genotypes. A worked example where p = . 4, q = .

#### Why is there a 2 in 2pq?

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 2 2pq and Q2 represent?

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 2pq represent in the Hardy Weinberg formula?

1 Answer. Kieran W. Answer: In the Hardy-Weinberg equilibrium equation, the term #2pq# represents the genotype frequency of heterozygotes in a population in equilibrium (where #p^2# + #2pq# + #q^2# = 1 ).

### What does the sum of P and Q represent?

#p# represents the allele frequency of allele A, and #q# represents the allele frequency of the allele a. The sum of all of these terms is always equal to #1# (ie. #p^2 + 2pq + q^2 = 1# ) because those three frequencies represent all possible combinations of alleles.

### Is the frequency of 98 equal to Q2?

This means that these 98 also have the homozygous recessive genotype, the frequency of which is equal to q2. To determine what the actual frequency is, simply divide 98 200 = 0.49. We now know that q2 = 0.49.
