There are three different types.
1) Ia
2) Ib
3) Io
They are weird alleles as both Ia and Ib are co-dominant but Io is recessive
IaIa=A
IaIb=AB
IbIb=B
IaIo=A
IbIo=B
IoIo=O

∙ 9y agoThere are up to 9 separate genes known to have some sort of impact on human blood type. These genes are typically observed on chromosome number 9.

What is the blood type in humans controlled by?
Blood types are controlled by multiple alleles.
What are blood types of humans examples of?
Blood type in humans is an example of multiple alleles.
The ABO blood types are controlled by?
ABO blood types are controlled by codominance and multiple alleles.
What type of alleles are there?
Some types of alleles are: blood type, hair color, hair type, eye color, etc.
Blood types in humans are an example of traits controlled by?
Multiple alleles
How do you describe how blood groups are examples of multiple alleles and codominance?
Because both factors are present; when we talk about blood types, we have 2 individuals with 2 different blood types and they become codominant within the reproduction; meaning, there is a set of alleles and both of them show in the phenotype.
What is an example of a trait inherited by multiple alleles?
The best example possible; blood types!
When two alleles are both dominant for the same trait an in blood types they are?
Homozygous dominant
Which two terms best describe the inheritance of human blood types?
codominance and multiple alleles
Why o blood can only receive blood o?
O blood type can only receive O blood type because in genetic, O is has recessive alleles while other types of blood has codominant alleles. A recessive alleles cannot combine with dominant or codominant allels. So if a person who has blood type O receive the other types of blood besides O, the blood cells within that person is going to repel each other. The worst situation, the person can die.
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.
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.
