Question

Calculate phenotype frequencies in 5th generation. Record in Lab Data

Answer 1

Answer:

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
