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 hors, is dominant over the allele for having homs (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/homed
B.12 black/polled: 0 black/homed: 0 red/polled : 4 red/homed
C.4 black/polled . 4 black/homed : 4 red/polled : 4 red/homed
D.9 black/polled : 3 black/horned : 3 red/polled : 1 red/homed
