A person’s blood type is based on whether or not they have certain molecules or proteins — called antigens — on the surface of their red blood cells, according to the National Institutes of Health. Two of the main antigens used for blood typing are known as “A antigen” and “B antigen.” People with type A blood only have A antigens on their red blood cells and those with type B blood have only B antigens. Individuals with type AB blood have both; people with type O blood have neither.


Another protein, the “Rh factor” – also known as the “Rhesus” system – is also present or absent on red blood cells. A person’s blood type is designated as “positive” if they have the Rh protein on their red blood cells, and “negative” if they don’t have this protein.

A person’s blood type is genetic, inherited from his or her parents, according to the Red Cross.

Blood typing is particularly important for blood transfusions, because certain antigens on blood cells can trigger a person’s immune system to attack the donated blood.

People who are Rh-negative can only receive Rh-negative blood, but people who are Rh- positive can receive either Rh-positive or Rh-negative blood, the Red Cross says.

What’s more, type A blood can be used for transfusions for patients with type A or type AB blood; type B blood can be used for patients with type B or type AB blood; and type AB blood can be used for patients with type AB blood. People with type O blood are called “universal donors” because this type can be used for patients with any blood type.

Type O blood is often in short supply in hospitals, due to demand for this universal donor type, according to the Red Cross. In particular, type O-negative blood is in high demand because it’s the one most often used for emergencies, when there may not be time to determine a patient’s blood type.

  1. RH- negatives seem to more ancient line than even apes. Mainstream science censors the fact that “lack of antigen” isn´t a random mutation, but RH-negatives have different proteins, amino acids and nucleotides even in their brains. The international Encode project has found out that fifth of the human genome codes and regulates proteins (which are different in pure Caucasian RH-negatives). Differences go in RNA, which also indicates to another species and another “evolution” path. This, of course is a difficult subject to so called elite formed of rhesus/ape humans. There is a short video about this subject, also a petrified fossil that could be one of the ancestors of Rh-negatives and there´s not any hint of apes in that humanoid fossil much older than apes.

    There are numerous remnants of ancient advanced civilization, which likely manipulated genetically also ape humans. As a matter of fact, modern ape humans are an unnatural creation, talking apes, animals of hunter-gatherer background without any high cultural achievements of their own. And these apes try to write (or simply censor) also history of more developed cultures.

  2. Just for conversation’s sake: strictly scientifically speaking, a species is defined as a group of organisms, which can inter-breed successfully and exchange genes. As an illustration, the Pekin duck is one species. The Muscovey is another. They can breed, but the offspring produced is sterile and referred to as “mules”.

    Correspondingly, individuals with a negative blood type are, based strictly on science, a different species altogether. Unless medical science intervenes, an RH negative mother interbreeding with a positive blood type will create a deathly ill fetus/baby. The maternal body will begin to produce antibodies in order to “kill” off an invader (the developing fetus). A live baby born with blood type incompatibility will likely have serious medical complications also requiring of medical intervention.

    Neg and pos…different species of humanity.

    • Katyn, Erythroblastosis fetalis or hemolytic disease of the newborn is what results from a baby being RH positive (inherited from the father) and the mother being Rhesus Negative. When the mother’s blood is exposed to the fetal blood, she will produce antibodies that can attack the fetus’s red blood cells in such a way that the fetus’s red blood cells will be destroyed and there must be an acceptable number of
      RBCs or the fetus/newborn will die from heart failure. This can also result from any pregnancy of this combination, even that ending in abortion or miscarriage since the mother’s blood is sensitized and will attack subsequent RH positive fetuses. Usually the first birth does not result in harm to the fetus, but obviously the reaction gets worse as sensitization increases for each following pregnancy with RH positive babies. There is medication that can be given to the mother to prevent her from developing antibodies. Currently Rhesus-negative mothers who are pregnant with a rhesus-positive infant are offered Rho(D) immune globulin (RhIG, or RhoGam) at 28 weeks during pregnancy, at 34 weeks, and within 48 hours after delivery to prevent sensitization to the D antigen. These work by binding any fetal red blood cells with the D antigen before the mother is able to produce an immune response and form anti-D IgG antibodies. ALL humans are of the same species despite whether they are RH negative or positive. Mules result from the mating of a male donkey with a female horse. The resulting offspring will usually be sterile, but there have been mules who can reproduce offspring. Some female mules, when mated with a donkey or horse can produce offspring.
