What is ABO blood type caused by?

ABO blood group system, the classification of human blood based on the inherited properties of red blood cells (erythrocytes) as determined by the presence or absence of the antigens A and B, which are carried on the surface of the red cells. Persons may thus have type A, type B, type O, or type AB blood.

Is ABO blood type genetically inherited?

ABO Blood Type 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.

Are there any human diseases associated with the ABO blood group?

Results: The susceptibility to various diseases, such as cancer, cardiovascular diseases, infections and hematologic disorders, cognitive disorders, circulatory diseases, metabolic diseases, and malaria, has been linked with ABO blood groups.

Which blood type is most sensitive to disease?

People with types AB and B are at the greatest risk, which could be a result of higher rates of inflammation for these blood types. A heart-healthy lifestyle is particularly important for people with types AB and B blood.

Is ABO blood type rare?

There are dozens of blood typing systems, but most people are familiar with the ABO and Rh systems, which provide the eight basic blood types. Generally, AB-negative is considered to be the rarest blood type. However, because blood type is linked to genetics, there is no single type considered the rarest worldwide.

What is ABO blood type an example of?

The human ABO blood group system exhibits codominance. The system consists of three alleles A, B, and O. Both A and B are dominant in relation to O, and therefore blood group A can have the genotype AA or AO.

What type of inheritance is ABO blood?

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

What blood type lives the longest?

Life Span. Chances are higher you’ll live longer if you have type O blood. Experts think your lowered risk of disease in your heart and blood vessels (cardiovascular disease) may be one reason for this.

What is the rarest ABO blood type?

AB negative
What’s the rarest blood type? AB negative is the rarest of the eight main blood types – just 1% of our donors have it. Despite being rare, demand for AB negative blood is low and we don’t struggle to find donors with AB negative blood.

Can your blood type be ABO?

While several blood group systems are used to type your blood, ABO is the most important. Your ABO type is based on the presence or absence of two antigens (A and B) on the surface of red blood cells. There are four ABO types: A, B, AB and O.
