Answer 1

Hlo mate❤!

here is ur answer ⏬

✔The Rh blood group system is one of thirty-five known human blood group systems.

✔It is the second most important blood group system, after the ABO blood group system.

✔The Rh blood group system consists of 49 defined blood group antigens,

✔[1] among which the five antigens D, C, c, E, and e are the most important. There is no d ("little d") antigen.

✔Rh(D) status of an individual is normally described with a positive or negative suffix after the ABO

✔type (e.g., someone who is A Positive has the A antigen and the Rh(D) antigen, whereas someone who is A Negative lacks the Rh(D) antigen). The terms Rh factor, Rh positive, and Rh negative refer to the Rh(D) antigen only. Antibodies to Rh antigens can be involved in hemolytic transfusion reactions and antibodies to the Rh(D) and Rh(c) antigens confer significant risk of hemolytic!

Answer 2

RH-factor-

Landsteiner and Wiener discovered in 1940 That the surface of a human rbc's contains a protein that is found in the Rhesus monkeys. So, it is termed as RH-FACTOR

Those persons who have this factor is known as Rh-positive and the other as Rh-negative

Both Rh-positive and Rh-negative persons are normal. The problem only arises during bloid transfusion or in pregnancy
