January 08, 2021

You inherit one blood gene from your mother and one from your father. There are four possibilities.

Blood type is determined by the alleles that we inherit from our parents.

How is o blood type inherited. Each biological parent donates one of two abo genes to their child. A b and o. How is o positive blood type inherited.

The combination of genes determines your blood type. If parental blood groups consist of o and o the child s blood group will be o. Therefore a person may have a rh blood type and can still have an rh gene see the chart below.

Here s how it works. Everyone has an abo blood type a b ab or o and an rh factor positive or negative. Blood group o has neither a or b antigen on red cells but with both the a and b antibody in the plasma.

Click on a blood type below to see how it is. A a a a o a a b ab b b b b o b o o o. Get both an a version and a b version you ll have both types of antigens and your blood type will be ab.

The positive and negative at the end of your blood type is a completely separate entity from abo. I m going to ignore the and part of this a and b are dominant and o is recessive. The most common by far is blood type o followed by type a type b and the least common is blood type ab.

The a and b genes are dominant and the o gene is recessive. Therefore the blood type of your parents directly impacts what your blood type is. Abo and rh are the most well known among the blood group systems.

The rh factor is inherited separately from the abo blood types. Inheritance patterns of blood groups inheritance patterns of blood groups blood groups are inherited from our parents in the same way as other genetic traits eg eye colour. How is o negative blood type inherited.

Like eye color blood type is passed genetically from your parents. If mom gives you an o version and dad gives you an a version your blood type will be a since you ll only have a antigens. If parental blood groups consist of o and b the child s blood group will either be o or b.

Blood inheritance abo blood type. Whether your blood group is type a b ab or o is based on the blood types of your mother and father. If parental blood groups consist of o and o the child s blood group will be o.

When we inherit genes we. If parental blood groups consist of o and a the child s blood group will either be o or a. Blood type is an inherited trait that determines which kind of blood cells we produce.

O genes or alleles do not produce antigens a or b thereby are called silent alleles. A b ab and o. Alleles are different possible types of a particular gene in this case the gene s controlling our blood type.

Similarly to the masking effect of the o gene in abo blood types the rh negative rh gene is also masked by the presence of a rh positive rh genotype. There are three common blood type alleles. We all have two alleles one inherited from each parent.

Just like eye or hair color our blood type is inherited from our parents.
