what are the different types of blood groups in humans?

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.

The difference between blood group and blood genotype Within ABO blood group systems, there are four different blood groups; A, B, AB and O while for Rh D group system, there are two types - Rh D positive and Rh D negative. Blood genotype indicates of the type of protein (Haemoglobin) that is in the red blood cells.

The specific antigens that create the different blood types are found on the surface of red blood cells and are known as type A and type B. They're further separated by the presence of another type of antigen known as rH factor. ... Someone that has type A antigens and rH factor is considered to have type A+ blood.

The five main types of blood cells are basophils, neutrophils, eosinophils, monocytes, and lymphocytes. Basophils are the cells mainly responsible for allergic reactions. They defend against parasites and bacteria by excreting two chemicals: heparin and histamine. Heparin is a blood-thinning substance.

Examples of Multiple Alleles Two human examples of multiple-allele genes are the gene of the ABO blood group system, and the human-leukocyte-associated antigen (HLA) genes. The ABO system in humans is controlled by three alleles, usually referred to as IA, IB, and IO (the "I" stands for isohaemagglutinin).

The Rh blood group consists of several antigens - Rh(D), or D being the most important. O negative red blood cells lack the A and B antigens (hence, group O) and also the Rh(D) antigen. Rh null blood lacks all the antigens in the Rh group, such as D, C, c, E, e and others.

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.

Types. There are two major types of hemophilia, type A and type B. In hemophilia A, there is a lack of clotting factor VIII.
568626
Blood group AB has both A and B antigens, but no antibodies. Blood group B has B antigens with anti-A antibodies in the plasma. Blood group A has A antigens on the red blood cells with anti-B antibodies in the plasma.

Thirteen tests are performed on all donated blood, including: ABO blood grouping and Rh type, cholesterol, hepatitis (hepatitis B surface antigen, hepatitis B core antibody, and hepatitis C antibody), HIV (HIV-1 antibody, HIV-2 antibody, and HIV-0 antibody), HTLV (Human T-Lymphotrophic Virus Type I and II antibodies), ...

People with blood type O are considered to be universal donors. That is, they can donate blood to all other blood types. Why is this true? Blood type O does not have any A or B antigens and does have both A and B antibodies.
151952
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.

Dogs have more than 12 blood groups, and their red blood cells may contain any combination of these since each blood group is inherited independently. The most important of these is called Dog Erythrocyte Antigen (DEA) 1.1. Typing of blood donors and recipients is done before transfusion.
498954
Blood group A has A antigens on the red blood cells with anti-B antibodies in the plasma. This combination of antigens and antibodies determine which blood type you can be safely given for medical purposes.

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 following blood types are compatible: Donors with blood type A… can donate to recipients with blood types A and AB. Donors with blood type B… can donate to recipients with blood types B and AB. Donors with blood type AB… can donate to recipients with blood type AB only.
