What blood type can two parents make?

Two O parents will get an O child nearly all of the time. But it is technically possible for two O-type parents to have a child with A or B blood, and maybe even AB (although this is really unlikely). In fact, a child can get almost any kind of blood type if you consider the effect of mutations. How does this happen?

Can two blood type A Make O?

Even though both parents still have blood type A, Dad can pass on either his A or his O gene version. Mom can also either pass on her A or her O. Because of this, you can see that there’s 1 in 4 or 25\% chance for a child to have OO, or blood type O. How did I get a 1 in 4 chance?

Why do siblings have the same blood type?

Siblings may not have the same blood group. This results in various circumstances such as if both the parents are of type A (for instance), the the offspring will have a type of either A or AB. So, one of the siblings may have a blood type of A and the other with type AB. I hope you got it.

Which parent determines the blood type of the child?

Each biological parent donates one of their two ABO alleles to their child. A mother who is blood type O can only pass an O allele to her son or daughter. A father who is blood type AB could pass either an A or a B allele to his son or daughter.

Is blood type hereditary?

Blood types are determined by genetics. You inherit genes from your parents — one from your mother and one from your father — to create a pair. When it comes to blood type, you might inherit an A antigen from one parent and a B antigen from the other, resulting in the AB blood type.

How does inheritance of blood types work?

Just like eye or hair color, our blood type is inherited from our parents . Each biological parent donates one of two ABO genes to their child. 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.
