It does not usually cause problems.
It is an issue with blood transfusions and in tissue transplantation. The common place for it to be an issue is if an Rh negative mother has an Rh positive child. Some fetal blood mixes with the mother's and so she can make antibodies tot he Rh factor. If a later pregnancy is also Rh positive then the antibodies will kill that fetus. Doctors give Rhogam to Rh negative pregnant women in order to keep this from happening.
Rh factor is also called "Rhesus factor" because it was first discovered in the blood.

Rhesus monkey In fact, the scientific name of the monkey is "macacus rhesus"
Rhesus is a blood factor and a type of ape.

The antigen was first discovered in the blood of Rhesus monkeys.
The rh blood factor was first observed in Rhesus monkeys
Rh factor is named after the Rhesus monkey which was the source of testing. It refers to the plus or minus after one's blood type which determines compatibility.

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.
Rh Factor
The universal recipient for blood would be AB+, including positive for the Rh (Rhesus) factor.
