The brown skin trait is dominant over the black skin trait in cows. If two heterozygous brown skin cows are crossed, what is the brown-skinned offspring?

B = Brown Skin

b = black skin

                             B      b

                  B        BB   Bb

                  b         Bb   bb

Hope this helped :D

The chances of a homozygous brown skin cow is 25%

The chances of a heterozygous brown skin cow is 50%

The chances of a homozygous black skin cow is 25%

The chances of a heterozygous black skin cow is 0%
