Why Rh Negative is not Blood of Gods or of Alien Origin? Around 85% of humans are Rh positive, which means they have Rh D antigen in their blood, only around 15% are Rh negative which means they do not have Rh D antigen in their blood. This is also the reason why blood groups like O-ve are very rare. Back to the alien blood group theory which states that.

The Significance of Being Rh Negative or Rh Positive To put it simply, Landsteiner and Weiner discovered that blood types can be either Rh positive or Rh negative, doubling the commonly known blood types from four (A, B, AB, and O), to the eight we know today.

- Rhesus factor (rh) is a blood product – it’s a substance found in blood. Approximately 85% of the population has the rhesus factor and the remaining 15% percent do not. It is symbolised by the plus or minus after your blood group, for example, A-is rhesus negative and A+ is rhesus positive.

What's the Most Common Blood Type? Answer: The approximate distribution of blood types in the U.S. population is as follows: 1  O-positive: 38 percent. 2  O-negative: 7 percent. 3  A-positive: 34 percent. 4  A-negative: 6 percent. 5  B-positive: 9 percent. 6  B-negative: 2 percent. 7  AB-positive: 3 percent.ype AB-positive blood is called the universal recipient type because a person who has it can receive blood of any type. People over age 69 receive half of all transfusions of whole blood and red blood cells, according to the National Blood Data Resource Center (NBDRC).

Different Types of Blood Cells and Their Roles in the Human Body RBCs account for approximately 40 to 45 percent of the blood. This percentage of blood made up of RBCs is a frequently measured number and is called the hematocrit. The ratio of cells in normal blood is 600 RBCs for each white blood cell and 40 platelets. There are several things about RBCs that make them unusual:

How Blood Works Red blood cells (RBCs) are by far the most abundant cells in the blood. RBCs give blood its characteristic red color. In men, there are an average of 5,200,000 RBCs per cubic millimeter (microliter), and in women there are an average of 4,600,000 RBCs per cubic millimeter.

- Cro-Magnon theorists point out that other places known to have been occupied by Cro-Magnon man, such as the Atlas Mountains of Morocco and the Canary Islands, also have been found to have a high incidence of Rh negative. Twenty-seven percent of Basques have O Rh negative blood.

- What is Panda Blood? Rh-negative (A) blood type, is called Panda Blood by the Chinese people, because of its extreme scarcity, like the Panda. Among the majority Han ethnic population, only 3 out of every 1,000 have Rh-negative blood, and even fewer are A type (Rh-). Rh- Negative Origin Theories.

- Among the more than 50 different antigens capable of causing maternal alloimmunization and fetal hemolytic disease, the Rhesus (Rh) blood group system is the most common. The Rh blood system is comprised of the c, C, D, e, and E antigens. Of note, no d (pronounced little d) antigen exists.

The ABO Blood System and the Most Common Blood Type Rh+ blood types are more common than Rh- blood types. The most common blood type in humans is O+ (~36.4%). Next in line are blood types A+, B+ and AB- with percentages approximately 28.3%, 20.6% and 5.1% respectively. The least common blood type is AB- (~0.5%).

- Rh factor: An antigen found on the surface of red blood cells. Red blood cells with the antigen are said to be Rh positive (Rh+). Those without the surface antigen are said to be Rh negative (Rh-). Blood used in transfusions much match donors for Rh status as well as for ABO blood group, as Rh- patients will develop anemia if given R+ blood.

Blood type Rh disease can develop in these cases. Rh negative blood types are much less common in proportion of Asian populations (0.3%) than they are in White (15%). The presence or absence of the Rh(D) antigen is signified by the + or − sign, so that, for example, the A− group is ABO type A and does not have the Rh (D) antigen.

- If your blood has the protein, you're Rh positive. If your blood lacks the protein, you're Rh negative. Rh positive is the most common blood type. Having an Rh negative blood type is not an illness and usually does not affect your health.

Can an Rh negative mother and Rh positive father have an Rh negative baby? What is Rh positive and Rh negative mean? Rh factor is a protein that is found in the blood of about 85% of the population. Those who have the factor are Rh positive, while those who don't, are Rh negative. A person who is Rh negative can safely donate blood to persons with or without the protein. A person who is Rh positive can only donate to those who are Rh positive.

- Who are the only people who could have Rh antibodies. Rh - men or women who have been given an Rh + blood transfusion, or a woman who is Rh- and has an Rh+ baby and is not treated. Whole blood minus the clotting elements is called blood ________.

- Concerning RH negative blood, The Basques (are Neanderthals) have the highest percentage digestive problems and food allergies. Martians, blue eyed and blond hair, come from the Caucasus. Cro-Magnon had a higher cranial volume.

Frequently Asked Questions Blood is composed of plasma, red blood cells, white blood cells, and platelets. Plasma makes up approximately 55 percent of the volume of blood. About 7 percent of a person’s weight is blood. An average sized man has about 12 pints of blood and an average woman has about 9 pints.

Why Rh Negative is not Blood of Gods or of Alien Origin? While the ABO classification is based on the two antigens A and B, the Rh group has 50 antigens! However, the main Rh classification is based on one single antigen of special importance, called the D antigen. So, if your blood has the Rh D antigen, then your blood group is Rh positive, else it is Rh negative. The reason for the importance of this antigen is that a mismatch in the D antigen can prove fatal during blood transfusion, just like it does in AB antigen mismatch. So A+ve means a blood group which has A antigen and Rh D antigen. O-ve means a blood group which has neither A nor B antigens, nor Rh D antigen.

- Hence, it is our view that Rh+ (Rh-positive) is the original Rh blood allele in humans, since black Africans in Africa who have not mixed either with white populations or with mixed-race persons have ONLY this Rh allele and no evidence of Rh- (Rh-negative).

About 7 percent of a person’s weight is blood. An average sized man has about 12 pints of blood and an average woman has about 9 pints. Plasmapheresis is a plasma donation process in which you only donate the straw-colored “liquid” portion of your blood, the plasma. A needle is placed in the vein of the donor’s arm, and the blood is collected utilizing a highly specialized medical device approved by the Food and Drug Administration (FDA).

Blood Types in Pregnancy If a person has the genes + +, the Rh factor in the blood will be positive. If a person has the genes + -, the Rh factor will be positive. If a person has the genes - -, the Rh factor will be negative. A baby receives one gene from the father and one from the mother.

Rh blood group system For the band, see The RH Factor. The Rh blood group system (including the Rh factor) is one of thirty-five current human blood group systems. It is the second most important blood group system, after ABO, and it consists of 50 defined blood-group antigens, among which the five 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.

Blood Blood Types. There are four main blood types: A, B, AB and O. Approximately 82 percent of the population is Rh positive, while 18 percent is Rh negative. Type O+ blood is the most common, and most frequently used, blood type. Type O- is the universal blood donor, because most people can accept this type of blood regardless of their blood type.

More Detail on RH Negative Blood as Promised When we separate the ‘O’ types into ‘negative’ and ‘positive’ we find that ‘O’ negative (the universal donor blood) constitutes less than 7% of the world´s population. Science at this very time is attempting to create a synthetic RH negative ‘O’ blood, but without success.
