If a red cow (homozygous dominant) is crossed with a white cow (homozygous dominant), what alleles will the offspring have?

A.Rw
B.RW
C.rW
D.rw

Answer 1

it is b.rW since they both dominant

Answer 2

B. RW. Whenever something is dominant the letter will always be capitalized on a punnet square. Since both given animals are homozygous dominant then the answer should all be in capital letters. Since there are no recessive parents which is represented by lowercase letters.
