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.
