Answer :
To find the value of [tex]\( q \)[/tex] when the frequency of the allele [tex]\( p \)[/tex] is given, we need to remember that the sum of the frequencies of the two alleles must equal 1. This is rooted in basic principles of genetic frequency, where:
[tex]\[ p + q = 1 \][/tex]
Given that [tex]\( p = 0.68 \)[/tex], we can determine [tex]\( q \)[/tex] by rearranging the equation to solve for [tex]\( q \)[/tex]:
[tex]\[ q = 1 - p \][/tex]
Substitute the given value of [tex]\( p \)[/tex]:
[tex]\[ q = 1 - 0.68 \][/tex]
Perform the subtraction:
[tex]\[ q = 0.32 \][/tex]
Hence, the frequency of allele [tex]\( q \)[/tex] is [tex]\( 0.32 \)[/tex], therefore the correct answer is:
D. 0.32
[tex]\[ p + q = 1 \][/tex]
Given that [tex]\( p = 0.68 \)[/tex], we can determine [tex]\( q \)[/tex] by rearranging the equation to solve for [tex]\( q \)[/tex]:
[tex]\[ q = 1 - p \][/tex]
Substitute the given value of [tex]\( p \)[/tex]:
[tex]\[ q = 1 - 0.68 \][/tex]
Perform the subtraction:
[tex]\[ q = 0.32 \][/tex]
Hence, the frequency of allele [tex]\( q \)[/tex] is [tex]\( 0.32 \)[/tex], therefore the correct answer is:
D. 0.32
