Is type O blood recessive?

The ABO blood type is inherited in an autosomal codominant fashion. The A and B alleles are codominant, and the O allele is recessive.

How do you determine an offspring blood type?

Blood Inheritance The A and B genes are dominant and the O gene is recessive. For example, if an O gene is paired with an A gene, the blood type will be A. For instance, a parent with O blood with 2 O genes and a parent with A blood with 2 A genes will have an A blood type child with one A gene and one O gene.

Can O+ and B+ have a baby?

But someone who has a B and an O version only makes the B protein. They are B blood type but can pass the O onto their kids. So two B parents can make an O child if both parents are BO….Menu.

How can a child have O blood type and neither parent have o?

To be O, you usually need to get an O from both mom and dad. But an AB parent usually has an A and a B version, not an O. So they usually can’t have an O child.

Can a child have O blood group if parents have A and B blood group?

Yes, a child can have blood group O if both of his parents have blood groups A and B.

CAN A+ parents have O+ child?

Yes this is definitely possible. In this case, the most likely explanation is that dad is a carrier for being Rh- and mom is a carrier for blood type O. What happened was that dad and mom each passed both an O and an Rh negative to the baby. The end result is an O negative child.

Can O+ parents have a+ child?

That means each child of these parents has a 1 in 8 chance to have a baby with an O- blood type. Each of their kids will also have a 3 in 8 chance of having A+, a 3 in 8 chance of being O+, and a 1 in 8 chance for being A-….Odds for O- Blood Type.
