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 x BbPp cross if these alleles sort independently?
• A 16 black/polled : O black/horned : 0 red/polled : O red/horned
OB. 12 black/polled : O black/horned: 0 red/polled : 4 red/horned
O C. 4 black/polled : 4 black/hogned : 4 red/polled : 4 red/horned
OD. 9 black/polled : 3 black/horned : 3 red/polled : 1 red/horned
