Phenotypical proportion obtained in f2 generation explained, Biology

Assignment Help:

Considering the hybridization in a given trait like the color of the hair of a mammalian species (white/black) conditioned by a pair of different alleles under complete dominance (black dominant, B/ white recessive, w), how can the phenotypical proportion obtained in the F2 generation be explained? What is this proportion?

In the monohybridism conditioned by two different alleles the F1 generation presents only heterozygous individuals (Bw). In the F2 there is one individual BB, two individuals Bw and one individual ww. In the relation to the phenotype there are in F2 two black individuals and one white individual, since black is the dominant color. So that the proportion is 3:1, three black-haired to one white- haired.
