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.
What person does a person with AB blood have?
A person with phenotype AB blood must have genotype AB blood. Meaning that the person has inherited both A and B alleles.
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.
What is the offspring when the mother has blood type AB and the father has a blood type B?
Possible blood types are A, B, or AB. Basically, the offspring can be any blood type except for O.
Which of the following is determined by multiple alleles?
Blood type in humans is determined by multiple alleles: A, B, and O. Each person inherits two of these alleles, resulting in four possible blood types: A, B, AB, and O.
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).
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.
If father has blood type b and the mother is a what is the child blood group?
The child could be AB, A, B, or O. It all depends on what the genotypes are for the parents. If they are both homozygous dominant (AA and BB), they will have an AB child. If one is AA and the other BO, the child could be AB or A. Both A and B alleles are completely dominant over the O allele. They are codominant, however, and when a child receives both A and B alleles from her parents, he or she will be AB blood type.
The blood types A B AB and O are the result of what inheritance multiple allelic polygenic or simple dominant?
The blood types A, B, AB, and O are determined by multiple alleles. These alleles exist at the same gene locus on chromosome 9 and interact to create the different blood types. Each individual has two of these alleles, resulting in the ABO blood type system.
How many blood group in human?
You can either have AB, A, B, or 0. so in general 4 groups. But the blood groups A and B can be heterozygous or homozygous. Meaning Aa, AA or Bb, BB Answer The blood groups are A, B, AB and O. The blood genotypes are AA, BB, AB, AO, BO and OO. A and B are equally dominant alleles, thus explaining the existence of AB.
