Where does the positive and negative for blood come from?
The positive and negative blood types come from the presence or absence of certain antigens on the surface of red blood cells. Blood type A has A antigens, B has B antigens, AB has both A and B antigens, and O has neither A nor B antigens. The positive or negative designation refers to the presence or absence of the Rh factor antigen.
What antibodies do a person with A- have?
A person with A negative blood will form antibodies to Rh + and to B
Which of these determine a person's blood type and stimulate antibody formation?
Antigens determine a person's blood type. These antigens are present on the surface of red blood cells and stimulate the immune system to produce antibodies against incompatible blood types.
A persons blood type depends on the presence or absence of certain proteins called?
A person's blood type depends on the presence or absence of certain proteins called antigens on the surface of red blood cells. These antigens determine whether a person's blood type is A, B, AB, or O.
ABO blood groups are based on the presence of?
Antigens A & B. If the person inherits just A or B they will be in that blood group, but if they inherit both types of antigens they will be in the AB group, and if they inherit no antibodies they will be in the O group
What is b plus blood type?
Human blood contains antigens. Antigens can make one person allergic to the blood from another person. There are two main antigens, A and B. A person without either has type O blood. So a person can have type A blood, type B, or type O. Also a person can have a combination of A and B antigens and have type AB blood. In addition blood has an Rh factor, which can be positive or negative. So a person can be A positive or A negative, O positive or O negative, and so forth. B+ simply means a person has type B blood and is Rh positive.
What is type B blood?
Human blood contains antigens. Antigens can make one person allergic to the blood from another person. There are two main antigens, A and B. A person without either has type O blood. So a person can have type A blood, type B, or type O. Also a person can have a combination of A and B antigens and have type AB blood. In addition blood has an Rh factor, which can be positive or negative. So a person can be A positive or A negative, O positive or O negative, and so forth. B+ simply means a person has type B blood and is Rh positive.
A person who is B positive will have?
A person who is B positive will have B antigens on their red blood cells and anti-A antibodies in their plasma. This blood type is compatible for transfusion with B positive, B negative, O positive, and O negative blood types.
If red blood cells lack RH antigens the blood is called?
If red blood cells lack Rh antigens, the blood is called Rh-negative.
Where does the positive and negative for blood come from?
The positive and negative blood types come from the presence or absence of certain antigens on the surface of red blood cells. Blood type A has A antigens, B has B antigens, AB has both A and B antigens, and O has neither A nor B antigens. The positive or negative designation refers to the presence or absence of the Rh factor antigen.
What are the two antigens that are responsible for human blood typing?
The two primary antigens responsible for human blood typing are A and B antigens, which are found on the surface of red blood cells. These antigens determine an individual's blood type in the ABO blood group system, which includes types A, B, AB, and O. The presence or absence of these antigens, along with the Rh factor (positive or negative), defines a person's complete blood type.
how do i find a person with blood type a?
Blood types are based on having a or b antigens or neither a or b antigens in your blood. Race plays a role in blood typing, and between 16% to 40% of people have type a blood. Blood types are further broken down to positive and negative rh factors. In order to find out which blood type a person has, a simple blood test is used that will show not only the antigens but also the rh factor found in a person's blood.
Which type of blood is the universal recipient?
A universal donor can donate to any blood type. The only universal donor is 0 negative because it doesn't have an antigens. Antigens are things that fight off foreign objects in your body, like white blood cells. A universal recipient can receive any type of blood. The only universal recipient is AB positive.
How do co-dominant alleles work?
Co-dominant alleles are both expressed, because both are translated into RNA. One of the best examples of co-dominance is human A/B blood type. The thing that differentiates A and B blood types is the antigens found on the surface of the blood cells. A person with two alleles for A-type antigens will have only A-type antigens, and a person with two B-type alleles will have only B-type antigens. However, a person with one A-type allele and one B-type allele will have blood type AB. A third allele, O-type, has no antigens on the surface of blood cells, and so is only "expressed" in the phenotype if a person has two O-type alleles (and therefore no antigens on their blood cells.)
What antibodies do a person with A- have?
A person with A negative blood will form antibodies to Rh + and to B
Why does different blood types make you more unique?
O negative blood is the universal donor and can be given to any person with any type of blood. Other blood types can not do this because their antigens.
Which of these determine a person's blood type and stimulate antibody formation?
Antigens determine a person's blood type. These antigens are present on the surface of red blood cells and stimulate the immune system to produce antibodies against incompatible blood types.
