What would the alleles of a person with type AB blood be?

Is blood type AB multiple alleles?

Human blood type is determined by codominant alleles. There are three different alleles, known as IA, IB, and i. … The possible human phenotypes for blood group are type A, type B, type AB, and type O.

How many possible alleles can a person with AB blood produce?

Under normal inheritance patterns, the person with type AB blood will have one A allele and one B allele. They will give either allele to their children, who will receive a copy of the O blood type gene from the second parent. These children will all have either type A or type B blood.

What are the alleles for each blood type?

Human blood type is determined by codominant alleles. There are three different alleles, known as IA, IB, and i. The IA and IB alleles are co-dominant, and the i allele is recessive. The possible human phenotypes for blood group are type A, type B, type AB, and type O.

Does blood type have multiple alleles?

An excellent example of multiple allele inheritance is human blood type. Blood type exists as four possible phenotypes: A, B, AB, & O. There are 3 alleles for the gene that determines blood type.

Is blood type AB recessive?

Everyone has an ABO blood type (A, B, AB, or O) and an Rh factor (positive or negative). 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.

What are examples of multiple alleles?

Two human examples of multiple-allele genes are the gene of the ABO blood group system, and the human-leukocyte-associated antigen (HLA) genes.

What are the alleles for blood type AB?

Someone with blood type AB must have both the A and B alleles. The genotype must be AB. Someone with blood type O has neither the A nor the B allele.

How many alleles do you have for your ABO blood type?

For example, the ABO blood group system has three alleles that affect the expression of antigens on the surface of red blood cells: alleles A, B, and O. Both alleles A and B are expressed in individuals with the AB blood type.
