AB+ and AB- are the most rare
Blood is composed of cells suspended in a liquid.
The liquid portion is the plasma, from which therapeutic fractions and derivatives are made.
Suspended in the plasma are three types of cells:
Red cells: These carry Oxygen
White cells: These fight infection
Platelets: These stop wounds bleeding
The most common type of grouping is the ABO grouping. Red Blood Cells have a protein coat on their surface which distinguishes them. According to this blood is divided into four groups:
A (A protein is present), B (B protein is present),AB (AB protein is present)and O ( No protein is present).
There are subtypes under this grouping ( listed as A1, A2, A1B or A2B…) some of which are quite rare.
Apart from this there is another protein which plays an important part in the grouping of blood. This is called the Rh factor. If this is present, the particular blood type is called positive. If it is absent, it is called negative. Thus we have the following broad categories:
A1 Negative
A1 Positive
A1B Negative
A1B Positive
A2 Negative
A2 Positive
A2B Negative
A2B Positive
B Negative
B Positive
O Negative
O Positive
Blood groups are a classic example of multiple allelic inheritance
Blood groups are affected by genetic drift randomly, making it special.
Blood types are codes which determine what type of blood you have, such as A, AB, O,etc.
yes blood groups have nothing to do with reproduction.
The blood groups A, B, AB and O are the seperate blood types and within a blood type the blood may be Rh+ or Rh-.
No. Blood groups are inherited from your parents.
yes they do. they have at least 2 different blood groups.
In case any of you need an emergency blood transfer.
There are over 30 blood groups for horses, 8 of these are major groups and 7 are recognized internationally.
Blood groups are dertermined on the surface of the red blood cells and they have nothing to do with our immune system.
