antigen D is the most important
I assume what you are talking about is D antigen in Rh (Rhesus) blood group system. Rh blood group system is the most important blood group system after ABO blood group system (i.e. type A (AA, AO), type AB, type B (BB, BO), type O (OO) ). The Rh blood group system consists of 50 defined blood-group antigens and the 5 antigens D, C, c, E, and e are the most important. The commonly-used terms Rh factor, Rh positive and Rh negative refer to the D antigen only. Rh factor (Rh- and Rh + depending on D antigen neg/pos) is important for blood transfusion and prevention of hemolytic disease of the newborn or erythroblastosis fetalis (basically the baby and mom have different blood type - Rh- and Rh+ and cause severe immune response - fatal to the newborn)
because the d and the z had sex!

Anti D
Blood type D is not one of the four main blood type groups. There is a D antigen that is part of the Rh antigen system, but there is not a blood type group called blood type D.
"Lucy Locket" is a popular nursery rhyme that tells the story of a woman named Lucy who lost her pocket full of money. In music, "Lucy Locket" can refer to a simple melody used for teaching beginner students.

The significant Rh antigen most care about is D antigen and all A+, B+, AB+ or O+ blood types have the Rh Antigen. The positive is used to indicate the D antigen. There are different, in fact numerous kind of blood groups. While the ABO blood group is one example the Rh blood group is another one. The Rh blood group has 5 antigens: D C c E & e. Everyone has Rh antigens one or the other but out of Rh antigens the most important one is D. If a person has D anitgen then he/she is said to be Rh+ if not Rh-.
The D stands for nothing. It was discovered 4th after A, B, C and hence they named it as D.
