The phenotype frequency in the 5th generation is:

0.057

According to the given question, we can see a table which contains the values of Environment, Phenotype Frequency and Allele Frequency and we are asked to calculate the phenotype frequency in the 5th generation.

As a result of this, we can see that we have to use the values of the Typica phenotype (white), the Carbonaria phenotype (black) and the total moths observed = 932 with the formula, Number of Typica phenotype/total moths in 5th gen.

With this in mind, we would get f (black) = 54/ 932 which would give us the value of 0.057

Therefore, the correct answer is 0.057

The number of moths in 5th generation (G5) with:

Typica phenotype (white) = 878

Carbonaria phenotype (black) = 54

total moths observed = 932

5th generation Phenotype frequency:

f (Typica) = Number of Typica phenotype in G5/ total moths in 5th gen

f (Typica) = 878/ 932

= 0.94

f (Carbonaria) = Number Carbonaria phenotype in G5/ total moths  in 5th gen

f (black) = 54/ 932

= 0.057
