Question
In humans, ABO blood types refer to glyocproteins 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 A type 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 O type 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 and B
AB and O
A, B, and O
A, B, and AB
A, B, AB, and O
Explanation / Answer

IA and IB are codominant, and i is recessive to both IA and IB.
People with A type blood have the genotypes IAIA or IAIO
people with type B blood are IBIB or IBIO
people with type AB blood are IAIB, and
people with O type blood are IOIO
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?
AB blood X O blood,
