What is the reason for different blood types?

What is the reason for different blood types?

Blood types are determined by the presence or absence of certain antigens – substances that can trigger an immune response if they are foreign to the body. Since some antigens can trigger a patient’s immune system to attack the transfused blood, safe blood transfusions depend on careful blood typing and cross-matching.

Why do family members have different blood types?

Blood types are inherited and represent genetic markers from both parents, so the answer to this question depends on the blood types of the parents. Each biological parent donates one of their two ABO alleles to their child. If both parents are Type A, for example, then their children must also all be Type A.

Do different nationalities have different blood types?

Due to this genetic factor, the American Red Cross suggest that when people need blood, especially those with rare blood types, the best matches tend to come from people of the same race or ethnic background. Inherited characteristics, such as blood types, tend to run in ethnic groups.

Why are some blood types more common than others?

Genetics, says Dr. Herron—it’s based on how populations spread to different parts of the world. “Every ethnicity has every blood group represented, but the different groups are present in different proportions,” he says.

Is there any problem if husband and wife have same blood group?

Blood group compatibility for marriage is limited to possible Rh factor incompatibility during pregnancy. And that is further limited to pregnancy where both partners are the biological parents.

What are the best blood groups?

So O-Neg and AB are the best blood groups! Answer: There are four recognised groups – O, A, B and AB – which refer to the marker (antigens) carried on the surface of the blood group – A carries the A antigens etc. B the B antigens and other cells recognise A antigens as the enemy, so carry anti-A.

What are the types of blood groups?

There are four main blood groups (types of blood) – A, B, AB and O. Your blood group is determined by the genes you inherit from your parents.

What are all the names of all the blood types?

There are basically four main blood groups or types and they are A, B, AB, and O. They are further divided into what is known as the Rh system which expands the blood types to eight categories and they are A(+), A(-), B(+), B(-), O(+), O(-), AB(+), and AB(-).

What are the 8 different blood types?

People are probably most familiar with these types because they include the eight common blood types: A-positive, A-negative, B-positive, B-negative, AB-positive, AB-negative, O-positive, and O-negative.
