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.
How many alleles control blood type in humans?
2
Is the three alleles of the single gene that controls blood type is said to be what alleles?
multiple alleles
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.
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
An example of multiple alleles?
Blood type.
Blood type is an example of what?
mulitple alleles
What type of alleles are there?
Some types of alleles are: blood type, hair color, hair type, eye color, etc.
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.
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.
Multiple alleles can be studied only in individuals?
Multiple alleles can be studied only in populations, not individuals. An example of multiple alleles would be blood type, each person has only one blood type, but a population has a many permutations.
What determines the blood type of a new born?
The alleles of the parents determine the blood type of the new born baby. If you do not know what alleles are they are different types of one gene. In the case of blood each person has two alleles. If you have type A you are two options of alleles: IaIa and IaIo If you are type B: IbIb and IbIo If you are type AB: IaIb If you are type O: IoIo For type A and Type B you have two options because the type O is recessive and can only be a full type by itself. You can predict what type of blood your child will have by making a punit square (a little chart multiplying both sets of alleles) of the two parents blood types.
