BIG POINTS PLEASE HELP In Holstein cattle the allele for black hair color (B) is dominant over the allele for red hair color (b) , and the allele for polled
(P), or lacking horns, is dominant over the allele for having horns(p).

What is the expected phenotypic ratio of the offspring of a BbPp × BbPp cross if these alleles sort independently?

A 16 black/polled : 0 black/horned : 0 red/polled : 0 red/horned

B 12 black/polled : 0 black/horned : 0 red/polled : 4 red/horned

C 4 black/polled : 4 black/horned : 4 red/polled : 4 red/horned

D 9 black/polled : 3 black/horned : 3 red/polled : 1 red/horned
