What is the probability of the offspring having brown eyes (dominant) if the father has the "bb" genotype and the mother has the "BB" genotype? You must create your own Punnett Square. *

1 or 100%

Explanation:

Assuming that the allele B (brown) is dominant over the allele b, crossing the father and the mother:

          BB    x    bb

      Bb    Bb    Bb    Bb (you can also see the Punnet's square)

All the offspring would exhibit the dominant phenotype which is brown. Hence, the probability of the offspring having brown eyes is 100% or simply 1.
