It all depends on the presence or not of antigens, kinds of markers , A or B on the surface of red blood cells. Thus, red blood cells of blood group A possess antigens A, those of group B antigens B, those of group AB antigens A and B whereas those of group O do not contain antigens.
That’s for the O, now for the sign – it’s called the Rh factor . Again it depends if there is an antigen on the surface of the red blood cells but another than the A and B. it is the D! If anyone can tell us why we jumped the C, it would help us! Just a small detail Rhesus was the name of a macaque that was used to make the first serum to test the Rhesus groups.
When transfusing blood, you know that you have to be careful, because, let’s simplify, if you are for example B and you receive A, your body will feel aggrieved by the markers A and will reject the blood with catastrophic consequences.
This is the interest of people in O- group, they have virtually no distinctive sign on the surface of their red blood cells, so they are very sought-after universal donors.

Group O is the primitive blood group of our ancestors who were offensive and cunning predators. Group O people occupy an important place in society.
What makes you unique?
Because of their blood type they are predisposed to certain diseases, such as ulcers and thyroid dysfunction. Blood group O often has low levels of thyroid hormone and iodine. This leads to a tendency to obesity, water retention and fatigue.

The most wanted O negative group
People whose blood type is O negative are often called “universal donors” because they can give blood to people of all blood types. Their red blood cells do not have any antigen rejected by the different blood groups.
In the blood, there are naturally antibodies directed against antigens that the blood does not have. Therefore, someone who has a blood group A can not receive blood from a group B or AB.
Receiving O negative group donations is a priority. In addition, people in the O negative group can only receive blood from their own group.
