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 four human groups are controlled by three alleles instead of two?
blood
What is a trait controlled by three or more alleles have?
multiple alleles
Is the three alleles of the single gene that controls blood type is said to be what alleles?
multiple alleles
How do multiple alleles control the trait?
In the case of multiple alleles, one trait is governed by more than two alleles. One example is the human ABO blood group. There are three alleles, A, B, and O. A person can, however, only inherit two of the three 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
What four human groups are controlled by three alleles instead of two?
blood
What is a trait controlled by three or more alleles have?
multiple alleles
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.
How many alleles go into polygenic inheritance?
three or more, or multiple
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.
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.
How blood type is inherit?
Blood type is controlled by multiple alleles. Blood type is inherited by three alleles, one A, one B, and an O, which is recessive Ex. A= IAIA IAi B= IBIB or IBi AB= IAIB O=ii
What are three different alleles used to represent blood type?
The three alleles are A, B, and O
Is the three alleles of the single gene that controls blood type is said to be what alleles?
multiple alleles
How is inheritance be multiple alleles and poly genic inheritance similar?
Multiple alleles is when there are more than 2 alleles in a single trait. In blood type, instead of either one dominant and one recessive type alleles, there is one recessive allele (type O) but two dominant alleles(type A and B). Polygenic inheritance is when more than one gene controls a single trait, such as height in which three genes are responsible.
Polygenic traits are controlled by no more than three alleles?
No, they are controlled by only two or more traits
What three ways are human traits controlled?
Single genes with two alleles, single genes with multiple alleles, and many genes that act together
