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 is a gene that has 3 or more alleles for a single trait?
An example of a gene with three or more alleles for a single trait is the ABO blood group gene. This gene has three main alleles - A, B, and O - which determine blood type. The different combinations of these alleles result in the various blood types (A, B, AB, and O) observed in humans.
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 do you describe how blood groups are examples of multiple alleles and codominance?
Because both factors are present; when we talk about blood types, we have 2 individuals with 2 different blood types and they become codominant within the reproduction; meaning, there is a set of alleles and both of them show in the phenotype.
Blood type in humans is controlled by how many alleles?
Blood type in humans is controlled by three alleles at the ABO gene locus on chromosome 9. These three alleles are responsible for determining the blood types A, B, AB, and O. Each person inherits one allele from each parent, resulting in various blood type combinations.
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.
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 are the 3 alleles for blood types?
The three alleles for blood types are A, B, and O. These alleles determine the presence of specific antigens on the surface of red blood cells. The A and B alleles are co-dominant, meaning that if both are present, both antigens will be expressed, resulting in blood type AB. The O allele is recessive, so it will not produce any antigens if paired with either A or B.
What is a gene that has 3 or more alleles for a single trait?
An example of a gene with three or more alleles for a single trait is the ABO blood group gene. This gene has three main alleles - A, B, and O - which determine blood type. The different combinations of these alleles result in the various blood types (A, B, AB, and O) observed in humans.
Blood type in humans is controlled by which alleles?
Human blood type is determined by codominant alleles.
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).
Why does the baby have only two alleles if the inheritance of blood type is controlled by three alleles?
Blood type inheritance is determined by three alleles (A, B, O), but an individual inherits only two alleles, one from each parent. This means a baby can have only two alleles for blood type, such as AO or BO, even though three alleles exist in the population.
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.
What is the a blood type for alleles?
Blood type is determined by the presence of specific alleles for the ABO blood group system. There are three main alleles: A, B, and O. The A and B alleles are co-dominant, meaning that if both are present (genotype AB), both antigens are expressed on the red blood cells. The O allele is recessive, so an individual must have two O alleles (genotype OO) to express the O blood type.
How do you describe how blood groups are examples of multiple alleles and codominance?
Because both factors are present; when we talk about blood types, we have 2 individuals with 2 different blood types and they become codominant within the reproduction; meaning, there is a set of alleles and both of them show in the phenotype.
The blood type trait which is controlled by more than two alleles for a given gene and therefore is called?
The blood type trait that is controlled by more than two alleles for a given gene is known as the ABO blood group system. It involves three alleles: A, B, and O, which determine blood types A, B, AB, and O. This system results in four possible blood types due to the combination of these multiple alleles.
Blood type in humans is controlled by how many alleles?
Blood type in humans is controlled by three alleles at the ABO gene locus on chromosome 9. These three alleles are responsible for determining the blood types A, B, AB, and O. Each person inherits one allele from each parent, resulting in various blood type combinations.
What is the relationship between LM and LN alleles?
The LM and LN alleles are related to the ABO blood group system, specifically in the context of the MNS blood group system. Individuals can inherit different combinations of these alleles, leading to varying phenotypes, such as MM, MN, or NN. The presence of LM and LN alleles can influence blood transfusion compatibility and susceptibility to certain diseases. These alleles are important in blood typing and genetic studies.
