Consider the genetic cross for fur color. what is the probability that the offspring of this cross will have black fur?

The black fur is dominant over white(light) colour which means black fur trait only require one copy of allele to express itself.

Key

B=black

b=white

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%.
