Which blood type is always heterozygous?
AB blood type is always heterozygous because it carries both A and B 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.
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.
What are 3 blood alleles?
Three common blood alleles are A, B, and O. A person's blood type is determined by the combination of these alleles. People with type A blood have A alleles, people with type B have B alleles, people with type AB have both A and B alleles, and people with type O have neither A nor B alleles.
If Jane and her husband were type AB cold they have a type O daughter?
No, Jane and her husband cannot have a type O daughter if both parents are blood type AB. Blood type is determined by the alleles inherited from each parent, and type AB individuals can only pass on A or B alleles. Therefore, any children they have would inherit either type A or type B blood, but not type O, which requires two O alleles.
What is the blood type of person who is heterozygous having A and B alleles codominant?
Blood types is a good example of codominance. There are three alleles for blood type, that can be represented as IA, IB, and i. IA and IB are both dominant to i, but when an individual inherits one of each the former two alleles (IAIB), he or she will have type AB blood. Instead of one allele being straightforwardly dominant to another, or the resulting phenotype being a halfway stage between the two alleles, the phenotype has aspects directly resulting from each allele.
Is ABO blood group determined by multiple alleles?
Yes, the ABO blood group system is determined by multiple alleles. There are three main alleles involved in the ABO blood group system: A, B, and O. These alleles determine the presence or absence of specific antigens on red blood cells, which results in the different blood types (A, B, AB, or O).
When one allele does not mask the other and both show AB blood type?
This is an example of co-dominance in which both alleles are expressed equally.
Which blood type is characterized by codominance?
The blood type AB is characterized by codominance because both the A and B alleles are expressed equally on the surface of the red blood cells. This results in individuals with blood type AB having both A and B antigens present.
In AB blood the A and the B alleles have what?
They have codominance.
What is an example of multiple alleles?
An example of multiple alleles is the ABO blood system in humans, where the gene for blood type has three alleles: A, B, and O. Each person inherits two of these alleles, resulting in four possible blood types: A, B, AB, and O.
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
