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

Nhumans, abo blood types refer to glycoproteins in the membranes of red blood cells. there are three alleles for this autosomal gene: ia, ib, and i. the ia allele codes for the a glycoprotein, the ib allele codes for the b glycoprotein, and the i allele doesn't code for any membrane glycoprotein. ia and ib are codominant, and i is recessive to both ia and ib. people with type a blood have the genotypes iaia or iai, people with type b blood are ibib or ibi, people with type ab blood are iaib, and people with type o blood are ii. if a woman with type ab blood marries a man with type o blood, which of the following blood types could their children possibly have? in humans, abo blood types refer to glycoproteins in the membranes of red blood cells. there are three alleles for this autosomal gene: ia, ib, and i. the ia allele codes for the a glycoprotein, the ib allele codes for the b glycoprotein, and the i allele doesn't code for any membrane glycoprotein. ia and ib are codominant, and i is recessive to both ia and ib. people with type a blood have the genotypes iaia or iai, people with type b blood are ibib or ibi, people with type ab blood are iaib, and people with type o blood are ii. if a woman with type ab blood marries a man with type o blood, which of the following blood types could their children possibly have? a, b, ab, and o ab and o a, b, and o a and b
