Where,
B=black
b=white
Provided that the genetic cross is between genotype (BB) and (bb).
so, the probability that the offspring of this cross will have black fur is 100%.
2. Provided that the genetic cross is between genotype (Bb) and (bb).
so, the probability that the offspring of this cross will have black fur is 50%.
