PATHOLOGY

Detailed explanation-1: -Blood type is inherited through an inheritance pattern called codominance. In humans, red blood cells have proteins with sugars attached to the surface of red blood cells.

Detailed explanation-2: -Codominance. In people, one codominant trait that you can’t really observe by looking at a person, but many people know about themselves, is blood type. People with the AB blood type have one A allele and one B allele. Because both alleles are expressed at the same time, their blood type is AB.

Detailed explanation-3: -An example of this is in humans with Type AB blood. A person with AB blood type is a heterozygote. They inherit the allele for A blood from one parent and the allele for B blood from another parent. As a result of codominance, both expressions of type A and B blood are present.

Detailed explanation-4: -The ABO blood type is inherited in an autosomal codominant fashion. The A and B alleles are codominant, and the O allele is recessive.

Detailed explanation-5: -If you inherit an A from one parent and an O or A gene from another parent, you will have type A blood. Type B from one parent and type O or another type B gene from the other parent will give you type B blood. But inherit an A gene from one parent and a B from the other and you have AB type blood.
