A trait has two alleles, represented by [tex]\( p \)[/tex] and [tex]\( q \)[/tex]. If [tex]\( p = 0.22 \)[/tex], what is [tex]\( q \)[/tex]?

A. 0.78
B. 0.88
C. 0.22
D. 0.47



Answer :

To determine the value of [tex]\( q \)[/tex] for a trait with two alleles [tex]\( p \)[/tex] and [tex]\( q \)[/tex], where [tex]\( p = 0.22 \)[/tex], we need to use the principle that the sum of the probabilities of both alleles must equal 1. This is based on the basic concept of allele frequencies in genetics, where:

[tex]\[ p + q = 1 \][/tex]

Given that [tex]\( p = 0.22 \)[/tex], we can find [tex]\( q \)[/tex] by rearranging the equation:

[tex]\[ q = 1 - p \][/tex]

Substitute the given value of [tex]\( p \)[/tex]:

[tex]\[ q = 1 - 0.22 \][/tex]

Thus, we have:

[tex]\[ q = 0.78 \][/tex]

Therefore, the correct answer is:

A. 0.78
