NEGATIVE BLOOD TYPE
Negative Blood type is only one of the individual, racial and ethnic differences in Blood type and Negative and its composition. The ABO Blood group system was discovered in 1901 and since it is of major importance in medicine, samples have been diligently collected from the most remote of people groups for a century. Of no other human characteristic is so much data available. Most populations have migrated and mixed. Unfortunately the reliability of the Negative Blood data for assessing relationships between population groups is very limited. This is mostly due to the lack of availability of this important data. As the chart reveals, the frequency and purity of the four main ABO Blood groups varies in populations throughout the world. A great variation may even occur in different groups within a given country; even a small country, as one ethnic group mixes, or not, with another.
As an example, the early European races are characterized by a very low type B frequency, and a relatively high type A frequency while the Asiatic races are characterized by a high frequency of types A and B. The following chart does not consider Rh factor and may vary in specific regions. It is also different for some very particular racial or ethnic groups. We have highlighted interesting pure anomalies.
The frequency with which Negative Blood types are observed is determined by the frequency with which the three alleles of the ABO gene are found in different parts of the world. Variation in this allele frequency of the ABO gene reflects the social tendency of populations to marry and reproduce within their national, regional, or ethnic group. As people throughout the world intermingle to a greater degree, the distribution of the different Blood types will continue to become more uniform. Red cell antigens are the phenotypical expression of our inherited genes. One of the most common questions that we get is about the the ethnic and racial distribution of human Blood groups. In response, following here is our collection of basic ABO Blood group data, sorted by people groups.

One note; we do not consider the very small percentage of individuals who inherit unusual combinations of "minor" antigens. Everyone carries substances on their red Blood cells, called antigens. In addition to the well known ABO classified groupings, and Rh factor, there are over 260 "minor" antigens that have been identified. These antigens may appear in varying combinations. The presence or absence of these specific "minor" antigens single out that particular Blood type as being "rare." All Blood types are inherited and therefore certain rare Negative Blood combinations are more common in specific ethnic and racial groups. We recommend a review this subject HERE.
There is precise and up-to-date data available. These racial and ethnic Blood typing and population migration statistics are very important in modern medicine for many reasons. The overriding problem in obtaining and publishing this information in the United States, and to a slightly lesser extent in Western Europe, is political correctness. It is not nice to talk about the ways that I may be different from you
"..... In the
past, a person with blood type O negative blood was considered to be a
universal donor. It meant his or her blood could be given to anyone,
regardless of blood type, without causing a transfusion reaction. This is
no longer a relevant concept because of a better understanding of the
complex issues of immune reactions related to incompatible donor blood
