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.
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
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.
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.
How are multiple alleles different from polygenic traits?
Multiple alleles are genes that have more than two alleles. An example of this would be blood types, with ABO as three separate alleles.Polygenic traits are traits whose phenotype rely on alleles from different genes. An example of this would be hair type, which relies on genes from different parts of chromosomes.The main difference is that multiple alleles are genes with 3 or more alleles; polygenic traits do not necessarily have more alleles, but they rely on on multiple genes.
What are 3 blood alleles?
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
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.
What is multi alleles?
A multi-allele trait is one that 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.
What three or more forms of a gene that code for a single trait called?
A gene can have multiple forms, which are called Alleles. While a single gene may code for a trait in an organism, when multiple alleles exist for that gene, each different may produce a different character of that trait. For example, a person has two copies of the gene that codes for ABO blood type. There are three different alleles for this gene, A, B and O. This results in six different combinations of the alleles that the person can have (the genotype), which in turn results in four expressions of the gene in the person (called the phenotype), which is the blood type of the person.
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.
What four human groups are controlled by three alleles instead of two?
blood
