The D antigen in the Rh system determines whether you have positive or negative blood. If you have the Rh D antigen, your blood type is positive. If you lack the Rh D antigen, your blood type is negative. 77% of our donors are Rh D positive.

There is a possibility that the siblings may have the same blood group. There is also another possibility that the siblings may have different blood groups. Everyone inherits two alleles of the gene, one from each parent. The combination of your two alleles determines your blood type.

Everyone has an ABO blood type (A, B, AB, or O) and an Rh factor (positive or negative). Just like eye or hair color, our blood type is inherited from our parents. Each biological parent donates one of two ABO genes to their child. The A and B genes are dominant and the O gene is recessive.

The universal plasma donor has Type AB blood. Group B can donate red blood cells to B's and AB's. ... Group A can donate red blood cells to A's and AB's. Group O can donate red blood cells to anybody. It's the universal donor.

Positive or negative blood If you have the Rh D antigen, your blood type is positive. If you lack the Rh D antigen, your blood type is negative. 77% of our donors are Rh D positive. There are four other main antigens in the Rh system.

AB +ve is the universal acceptor blood group or the universal receptors. Because AB+ individuals have all of the possible antigens and therefore are the universal acceptors as their immune system is used to seeing each of the antigens. This means it won't attack any of the antigens!

This includes the D antigen (Rh factor, baby), plus the other 50-something antigens in the group. This blood type is so rare that only 43 people on Earth have ever been reported to have it, and there are only nine active donors.

The ABO System Whether your blood type is A, B, AB or O depends on whether you have, or don't have, certain antigens (named A and B) on your red cells. The presence or absence of A or B antigens gives us four main blood types: A type blood has only A antigens on red blood cells.

blood group O – has no antigens, but both anti-A and anti-B antibodies in the plasma. blood group AB – has both A and B antigens, but no antibodies.

Blood groups. There are 4 main blood groups (types of blood) – A, B, AB and O. Your blood group is determined by the genes you inherit from your parents. Each group can be either RhD positive or RhD negative, which means in total there are 8 blood groups.

Answer From Rajiv K. Pruthi, M.B.B.S. For emergency transfusions, blood group type O negative blood is the variety of blood that has the lowest risk of causing serious reactions for most people who receive it. Because of this, it's sometimes called the universal blood donor type.

Positive or negative blood If you have the Rh D antigen, your blood type is positive. If you lack the Rh D antigen, your blood type is negative.

The rhesus protein is named for the rhesus monkey, which also carries the gene, and is a protein that lives on the surface of the red blood cells. This protein is also often called the D antigen.

Distribution of blood types There are 4 main blood groups: A, B, AB and O, of which group O is the most common. In the United States, the average distribution of blood types is as follows: O-positive: 38 percent. O-negative: 7 percent.

['When 2 O blood type parents meet they produce a child with only O blood type.', 'When parents with A blood type meet they can produce a child with either A or O blood types.']

Blood group B has B antigens with anti-A antibodies in the plasma. White blood cells fight infections. Blood group AB has both A and B antigens, but no antibodies. Both the ABO and the Rh blood types are important when it comes to matching blood types for transfusion.

Your blood can be Rh positive, which means that you have the Rh protein, or Rh negative, which means that you do not have the Rh protein. The letter of your blood group plus the Rh makes your blood type. You can be O+, O−, A+, A−, B+, B−, AB+, or AB−.
