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.

What is when an individual has two copies of a dominant allele?
When an individual has two copies of a dominant allele, they will display the dominant trait associated with that allele. Dominant alleles mask the expression of recessive alleles in a gene pair.
Is A heterozygous pair of alleles is identical?
When there are heterozygous alleles for a gene thy code for a different expression of the gene. For example, the gene to taste PTC paper is a single gene trait. A person will have two copies (or alleles) for that gene (one from their mothers DNA, one from their father). There are two possible expressions for this gene - either you can taste the chemical or you cannot. When one allele is for tasting, and the other for not tasting, this is known as heterozygous. Both alleles are relating to the same gene but they giving different instructions and are thus not identical. When this happens, the dominant gene wins - in this case tasting is expressed. If the alleles are identical, they are known as homozygous and they are identical.
What is a heterozygous person called?
A heterozygous person is called a carrier for the specific trait or gene they carry. This means they have two different alleles for a particular gene, with one dominant and one recessive allele. It is important to note that being heterozygous for a genetic disorder does not necessarily mean the individual will exhibit symptoms of the disorder.
A person with a heterozygous gene?
A person with a heterozygous gene has one dominant allele, usually represented by a capital letter, and a recessive allele, which is usually represented with a lowercase letter. So an example of a heterozygous gene would be Rr
What is a gene with two different alleles?
An example of a gene with two different alleles is the gene for human blood type, which can have alleles for blood type A, B, or O. Each person inherits one allele from each parent to determine their blood type.
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 is heterozygous?
Heterozygous refers to alleles that are not the same. For example, lets pretend that the gene for hair color is H for brown hair and h for blond hair. If someone was HH, they would be homozygous because the two alleles of the gene are the same. If a person was blond, their genes would have to be hh, which is homozygous recessive. Heterozygous is when the alleles are different, like so: Hh.
What is when an individual has two copies of a dominant allele?
When an individual has two copies of a dominant allele, they will display the dominant trait associated with that allele. Dominant alleles mask the expression of recessive alleles in a gene pair.
Why o blood can only receive blood o?
O blood type can only receive O blood type because in genetic, O is has recessive alleles while other types of blood has codominant alleles. A recessive alleles cannot combine with dominant or codominant allels. So if a person who has blood type O receive the other types of blood besides O, the blood cells within that person is going to repel each other. The worst situation, the person can die.
What term is used when both alleles are different?
The condition called in a case when you have a two different types of alleles is called as Heterozygous and when this is exactly the opposite that is when it has the alleles for the same source we describe such a condition as a Homozygous. This two terms are of most importance when you take the genetics
Is A heterozygous pair of alleles is identical?
When there are heterozygous alleles for a gene thy code for a different expression of the gene. For example, the gene to taste PTC paper is a single gene trait.

If the alleles are identical, they are known as homozygous and they are identical.
What does being heterozygous for a trait mean?
the 2 alleles of the gene for the trait are different on the 2 homologous chromosomesBeing heterozygous for a trait means that they have different alleles for a trait. For instance: Tt would be heterozygous and TT or tt would be homozygous because they are both eitehr little or big t's.it mean the gene is not pure or for example suppose a person is blood group A but actually he is having A and O; because O is recessive trait the gene express the A trait instead, making the person having blood group A.
What is a heterozygous person called?
A heterozygous person is called a carrier for the specific trait or gene they carry. This means they have two different alleles for a particular gene, with one dominant and one recessive allele. It is important to note that being heterozygous for a genetic disorder does not necessarily mean the individual will exhibit symptoms of the disorder.
If a person has one copy of each of two different alleles (ie Bb) for a given gene the person is for that trait.?
If a person has one copy of each of two different alleles for a given gene, they are considered heterozygous for that trait. In this case, the alleles are represented as "B" and "b," where one may be dominant and the other recessive. The phenotype expressed will depend on the dominance relationship between the alleles.
A person with a heterozygous gene?
A person with a heterozygous gene has one dominant allele, usually represented by a capital letter, and a recessive allele, which is usually represented with a lowercase letter. So an example of a heterozygous gene would be Rr
What is an example of a heterozygous genotype?
Genotype means the particular alleles an individual has alleles are just a kind of gene and a gene is a section of DNA which codes for a particular protein or characteristic in an organism. Heterozygous is when a person has 2 alleles for the same characteristic like hair you could have the allele for both blonde or brown hair but due to the blonde one being recessive (ie not as powerfull/strong), you would not know. So, an example would be WBWb: B = Brown b = blonde W= allele so for hair a heterozygous person would have the genotype WBWb.
What is a gene with two different alleles?
An example of a gene with two different alleles is the gene for human blood type, which can have alleles for blood type A, B, or O. Each person inherits one allele from each parent to determine their blood type.
