simply put. A B and O two copies of each allele per person. blood type a = ia ia OR ia io blood type b = ib ib or ib io Blood type o = io io Blood type AB = ia ib

∙ 10y agoAn allele is one of several different forms of one's genetic material that is found in a person's DNA. There are 3 different alleles that determine blood type. They are A, B, and O.

∙ 9y agoThe three blood type alleles are A, B, and O. The A and B alleles are codominant in blood types.

How many genes control blood type?
The genes for the others work in similar fashions, though certainly not all have three alleles. The other aspect of blood type which is of most interest to us is the Rh factor. Genetically, this is much simpler than the ABo system. It has only two alleles, one dominant (Rh-positive) and one recessive (Rh-negative).
Blood type in humans is determined by a single gene that has multiple alleles?
Each person has two alleles for their blood type, one dominant and one recessive. Except for type AB blood where the alleles are co-dominant. The allele for O blood is always recessive when paired with either an A or B allele.
Who determines your blood type?
Your parents determine your blood type. Your blood type is a cross of two alleles from the parent, one from each parent. Your parents could either give you AA, AO, AB, BB, BO or OO alleles, depending on which two alleles that they have.
When more than two different alleles control a trait?
The presence of more than two alleles that control a trait is called multiple allele. An example of this is the group gene of ABO blood that has three alleles.
Blood type in humans is controlled by how many alleles?
It's potentially 3. A,B,O. Not necessarily ALL of them though, I believe.
How many alleles are there for blood type-?
There are three alleles for blood type: IA=Blood type A IB=Blood type B i=Blood type O The alleles for blood type A and B are codominant so when someone contains the IA and IB alleles, their blood type is AB.
Blood type in humans is controlled by which alleles?
Human blood type is determined by codominant alleles.
Is the three alleles of the single gene that controls blood type is said to be what alleles?
multiple alleles

Is ABO blood group determined by multiple alleles?
* Type A alleles could be : IAIA or IAi* Type B alleles could be : IBIB or IBi* Type AB alleles : IAIB* Type O alleles : ii
Why does the baby have only two alleles if the inheritance of blood type is controlled by three alleles?
Everyone only has two alleles for blood type. The parents each pass one down to the child.
What are three different alleles used to represent blood type?
The three alleles are A, B, and O
In AB blood the A and the B alleles have what?
They have codominance.
Blood type is an example of what?
mulitple alleles
An example of multiple alleles?
Blood type.
What trait is controlled by a gene with multi alleles?
The ABO blood groups in humans are controlled by multiple alleles.
