if a trait is determined by two alleles, the sum of p and q is 1. Why is this true?

Sagot :

Answer:

The value of q is

q = 0.10

Explanation:

The sum of the frequency is equal to 1.

Therefore, we have the following equation:

p + q = 1

Substituting values we have:

0.90 + q = 1

Clearing the value of q we have:

q = 1 - 0.90

q = 0.10

A variant form of the gene is called an allele that can be dominant or recessive for a trait. The sum of the frequencies of all alleles must be 1 at the locus.

What is the Hardy-Weinberg equation?

According to the equation, the frequencies of the alleles in the population must be equal to 1. p is the frequency for a dominant allele and q is frequency for a recessive allele.

The Hardy-Weinberg equation can be given as,

[tex]\begin{aligned}\rm p+q &= 1\\\\\rm p^{2}+ 2pq +q^{2} &= 1\end{aligned}[/tex]

In the equation, the frequency of the purebred dominant genotype is shown as [tex]\rm p^{2}[/tex]and the purebred recessive genotype as [tex]\rm q^{2}[/tex]. The frequency of the heterozygous genotype is shown as, 2pq.

Therefore, the sum of p and q must always be 1.
