What is the abo identification system & the rh factor?

ABO identification system is the system of determining the blood type of the Human being by checking the presence of Antigens "A" & "B" on the surface of their RBCs. If A is present, then it is A Blood group, if B, then it is B blood group, if both, then AB and if neither then it is called as O blood group.

Rh Factor is the type by which we classify individuals into two groups - Rh +ve with Rh factor on their surface and Rh - ve, which lacks of it

Hope this helps!

The second major blood grouping system is the Rhesus (Rh) system. Like the ABO blood types, the Rh factor is an inherited blood protein, or antigen, on red blood cells.
