The Rh blood group is determined by a single gene with two alleles-- positive and negative. The positive (Rh+) allele is dominant, so persons who are Rh+/Rh+ or Rh+/Rh- are said to be Rh-positive. Individuals with two Rh- alleles are Rh-negative.

What else can I help you with?
Can a single gene control a sigle trait?
Its possible. A single gene defines a single protein.
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.
Is blood type a polygenic trait?
Blood type is not a polygenic trait. It is determined by multiple alleles of a single gene called the ABO gene located on chromosome 9. This gene has three common alleles (IA, IB, and i) that determine the ABO blood groups (A, B, AB, and O).
What is an example of a single gene with multiple alleles?
An example of a single gene with multiple alleles is the ABO blood group gene. This gene has three main alleles: A, B, and O, which determine an individual's blood type. Different combinations of these alleles result in the four blood types: A, B, AB, and O.
WHAT is single gene trait?
A single gene trait is a specific characteristic or phenotype that is influenced by the expression of a single gene. This means that the presence or absence of a particular trait is determined by variations in one specific gene. Examples include earlobe attachment, hair color, and tongue rolling.
Can a single gene control a sigle trait?
Its possible. A single gene defines a single protein.
What is an example of a human trait caused by a single gene with multiple alleles?
An example of a human trait caused by a single gene with multiple alleles is the ABO blood group system. This system is determined by the presence of different alleles at the ABO gene locus, specifically A, B, and O alleles. The combinations of these alleles result in four possible blood types: A, B, AB, and O, illustrating how multiple alleles can influence a single trait.
If your blood group is B-positive what must your parents be?
At least one parent has the 'positive' gene, but that is the only thing that can be determined.
What chromosome determine human blood group?
The ABO blood group system is determined by the ABO gene located on chromosome 9. This gene determines the presence of A and B antigens on the surface of red blood cells, which in turn determines a person's blood type (A, B, AB, or O).
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.
Is high blood pressure a dominant or recessive gene?
High blood pressure is not determined by a single gene, but rather by a combination of genetic, environmental, and lifestyle factors. This means that it is not a simple dominant or recessive trait, as it is influenced by multiple genes working together.
Is blood type a polygenic trait?
Blood type is not a polygenic trait. It is determined by multiple alleles of a single gene called the ABO gene located on chromosome 9. This gene has three common alleles (IA, IB, and i) that determine the ABO blood groups (A, B, AB, and O).
What is an example of a single gene with multiple alleles?

Mother has Group AB blood and father has Group O blood what can the child have?
We are looking for the possible blood types of a baby.Parental information:Mother type AB -- can offer the offspring Genes A & BFather type OO -- can only offer the offspring Gene OBaby receives one gene from each parent: Baby is type AOBaby is type BOThe baby can only get the O gene from his mother; therefore, whichever gene he gets from his father, the A or the B, is what his blood type will be.
WHAT is single gene trait?
A single gene trait is a specific characteristic or phenotype that is influenced by the expression of a single gene. This means that the presence or absence of a particular trait is determined by variations in one specific gene. Examples include earlobe attachment, hair color, and tongue rolling.
How do you use single gene trait in a sentence?
"now that it how the single gene trait is controlled"by the way stop cheating and seeing the answers online
What is one difference between single gene trait and a polygenic trait?
Polygenic traits result in more variation because so many more alleles are involved in the process of reproduction.
