A gene for feather color has two alleles, B which is dominant
over b. The presence of B
means black color and its absence means white color. Perform the
following crosses and
write out
(1) the phenotypic ratio of the progeny
(2) the genotypic ratio of the progeny under the following (a) BB ×
Bb; (b) Bb x bb; (c) Bb × Bb
Assuming you have I,000 chickens.
a) How many chickens will have white feathers under(a)?
b) How many chickens will have black feathers under(b)?
(c) How many chickens will have the genotype Bb under(c)?
