What are the 3 different alleles that one could inherit for blood type?

What are the three alleles that you can inherit for blood type?

There are three different alleles for human blood type, known as IA, IB, and i. For simplicity, we can call these alleles A (for IA), B (for IB), and O (for i). Each of us has two ABO blood type alleles, because we each inherit one blood type allele from our biological mother and one from our biological father.

What are the 3 types of genotypes?

There are three types of genotypes: homozygous dominant, homozygous recessive, and hetrozygous.

What allele determines your blood type?

Blood Type Is Determined Genetically

The A allele codes for an enzyme that makes the A antigen, and the B allele codes for an enzyme that makes the B antigen. A third version of this gene, the O allele, codes for a protein that is not functional; it makes no surface molecules at all.

What are the 3 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.

What are the three alleles responsible for ABO blood system?

The ABO locus has three main allelic forms: A, B, and O. The A and B alleles each encode a glycosyltransferase that catalyzes the final step in the synthesis of the A and B antigen, respectively.

Is BB a genotype?

An organism with two dominant alleles for a trait is said to have a homozygous dominant genotype. … In our example, this genotype is written Bb. Finally, the genotype of an organism with two recessive alleles is called homozygous recessive. In the eye color example, this genotype is written bb.

Is controlled by three alleles ABO?

Human blood is controlled by three alleles that create the ABO blood types. A and B are co-dominant, while the third allele, O, is recessive to the other two alleles. Below are a number of parent combinations. For each, indicate whether it could produce the resulting child.

Which allele for human blood type is recessive?

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 codominant, and the i allele is recessive.
