6. Considering hybridizationin
a given trait like the colour 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
two different alleles the generation
presents only heterozygous
(Bw). In F2 there one individual BB,
two Bw and one individual
. Inrelation to the phenotype
are in F2 two individuals and one
white , since black is the
colour. So the proportion
3:1, three black-haired to whitehaired.
