In studying the gene pool of a population, you find that 15% of the population is homozygous recessive (tt) for a trait. how would you use this information to solve for the frequency of the dominant t allele?

%

Explanation:

As per HARDY-WEINBERG LAW

represents the frequency of the dominant allele in the population

represents the frequency of the recessive allele in the population

represents the percentage of homozygous dominant individuals

represents the percentage of homozygous recessive individuals

represents the percentage of heterozygous individuals

Here the frequency of ‘tt” allele is

Thus,

Substituting this in below given equation, we get -

Frequency of T allele is represented by q.

Thus, frequency of T allele would be %

c is the correct answer!
