What type of alleles does a carrier have?
A carrier is heterozygous for a given trait. They would display the dominant trait but still be able to pass the recessive trait to their children.
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
A person with the alleles ii has what blood type?
Which statement describes the blood type of a person with the alleles IAi? It is type AB because I and i are codominant. It is type AB because A and i are codominant. It is type A because i is dominant and A is recessive. It is type A because A is dominant and i is recessive.
How do co-dominant alleles work?
Co-dominant alleles are both expressed, because both are translated into RNA. One of the best examples of co-dominance is human A/B blood type. The thing that differentiates A and B blood types is the antigens found on the surface of the blood cells. A person with two alleles for A-type antigens will have only A-type antigens, and a person with two B-type alleles will have only B-type antigens. However, a person with one A-type allele and one B-type allele will have blood type AB. A third allele, O-type, has no antigens on the surface of blood cells, and so is only "expressed" in the phenotype if a person has two O-type alleles (and therefore no antigens on their blood cells.)
The number of alleles of a certain type divided by the total number of alleles is what?
Alleles Frequency
Can a child be O positive if father is b positive and mother is a negative?
Yes. Blood type is determined by two alleles. A person with alleles AA or AO is considered type A, and a person with alleles BB or BO is considered type B. If the parents are AO and BO, they could both pass the O on to their child who would then be OO, type O.

A person receives an o allele and an A allele for blood type. what is the individual's blood type?
type A
What type of alleles mask recessive alleles?
Dominant 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.
What type of alleles does a plant have?
unlike alleles
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.
The number of alleles of a certain type divided by the total number of alleles is what?
Alleles Frequency
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.
