Answer:
33%.
Explanation:
The 4% population is red-hair due to the recessive mutation in melanocortin 1 receptor (MC1R).
Since, the population is in Hardy-Weinberg equillibrium- laet the frequency of recessive allele with red - hair is 'q' and the frequency of dominant allele in the population is 'p'.
q=0.2
According to hardy-weinberg equillibrium
(p+q)=1
p=1-q
p=1-0.2
p=0.8.
The total population with non red hair is calculated by
=
= 0.64 + 0.32
= 0.96
The percentage of the population with non red headed carrier for MC1Rr is calculated by:
=0.32/0.96*100
=33%
Thus, the correct answer is (B).
