It really did start with a rhesus monkey. There are four: O, A, B and AB. there is a factor, too. If you have it you are postive. If you don't you are negative. O is the most common and about 60% of people have it. About 30% have A. B is around 5% and the rarest, AB is about 2% O can donate to any other blood type depending upon the factor but can only give to itself. A can take O and B can, too. A can only give to A and B can only give to B. A person with the positive factor cannot give to someone with a negative factor and also the other way around. The rarest blood is AB negative and is found among the American Indians. there are also sub factors which usually occur as a result of having received blood. No blood factor is changed by donation of blood.
Rh factor is also called "Rhesus factor" because it was first discovered in the blood.
Rh factor is also called "Rhesus factor" because it was first discovered in the blood.
The antigen was first discovered in the blood of Rhesus monkeys.
The term "RH" stands for Rhesus factor, named after the Rhesus macaque monkey in whose blood the factor was first discovered in 1937. The RH factor refers to a specific protein present on the surface of red blood cells that can affect blood compatibility in transfusions and pregnancy.
To the second question the answer, in short, is YES; To answer the first question, there are four logical blood types: A, B, AB, and O. Then there is the Rhesus factor: either positive or negative. So there are actually eight types of blood a human can have: one of the above types with a negative Rhesus factor or with a positive Rhesus factor. Rhesus factor is a factor which compares human blood to a Rhesus monkey's blood. A negative result means your blood is not comparable to a Rhesus monkey. Blood types are inherited from your parents. If one parent has type A+, and the other has a B-, your blood type can either come out as A, + or -, or B, + or -, or the rare AB, + or - but not O. While type O negative is the universal donor, type AB positive is a universal recipient.
The rh blood factor was first observed in Rhesus monkeys
The universal recipient for blood would be AB+, including positive for the Rh (Rhesus) factor.
No, blood group O and blood group AB are ABO blood groups, while the rhesus factor is determined by the presence or absence of the Rh antigen on the surface of red blood cells. The ABO and Rh systems are independent of each other, so having blood group O or AB does not determine the presence or absence of the rhesus factor.
The rhesus monkey gave the Rh factor its name. The Rh factor is a protein found on the surface of red blood cells, originally discovered in rhesus monkeys before being identified in humans.

The Rh factor got its name from the Rhesus monkey, as they were first used in research to identify the presence of the protein in blood. This monkey's blood was instrumental in the discovery and understanding of the Rh factor in humans.
I think Rh is not a blood group. Rh stands for a factor and derived its name from factor found in the blood of Rhesus monkey.
