Of the human blood types, O is the most common. It is a universal blood type. Blood types are further broken down into two groups, negative and positive. This is called the RH factor. The RH factor is the Rhesus (rhesus as in monkey) blood factor. If your blood tests positive for this, you have the factor in your blood. If you test negative, you do not have the factor in your blood. The RH factor is a protein found in the human blood that is directly linked to the Rhesus Monkey.
But a person with Rh-blood can develop Rh antibodies in the blood plasma if he or she receives blood from a person with Rh + blood, whose Rh antigens can trigger the production of Rh antibodies. A person with Rh + blood can receive blood from a person with Rh-blood without any problems.
