In ABO Blood type, there are racial and ethnic differences in Blood type
and 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 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.
Great variation occurs in different groups within a given country; even
a small country, as one ethnic group mixes, or not, with another.
|The Blood type story today has changed and
mixed. ABO Blood types have survived for hundreds of millions of
years without being lost, or further diluted or mutated, generally
speaking. From the sampled distribution of Blood types around the
world today, we see adaptation by migration, environment, habitat
and region. Following is an overview of of Blood types, generally
considering present-day geography.
Blood Type O - Type O
Blood, which is known as the standard form of Blood types is
widely distributed over the whole world uniformly, where
populations have mixed.
Blood Type A - Blood
type A is seen widely Europe, especially prevalent in the heavily
forested and mountain zones.
Blood Type B - Blood
type B is seen in prairie and desert zones.
Blood Type AB - AB Blood
type exists only rarely globally, and is the Blood type generated
for the first time with the background where A type and B type
Publishing the ethnic
differences in Blood type and the racial differences in Blood type is
not, in the present-day world, considered to be politically correct. We
compile and maintain this database through often times confidential
sources. Every Blood gathering entity in the world must gather this
information to stay in business, but almost every one of them is afraid
to publish the racial and ethnic differences in Blood type, given the
emotionally charged political climate. Discount

For example, 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
The frequency with which
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 pheno-typical
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 Blood combinations are more
common in specific ethnic and racial groups. We review this subject . Discount

There is precise and
up-to-date data available. These racial and ethnic Blood typing and
population migration statistics are 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!

A Word about Blood-related DNA Genealogy and Anthropological Sampling
- The relatively new science of DNA research applied to full-blooded,
indigenous populations from around the world has led to the discovery
and documentation of genetic markers that are unique to populations,
ethnicity and/or deep ancestral migration patterns. The markers having
very specific modes of inheritance, which are relatively unique to
specific populations, are used, among other things, to assess ancestral
and kinship probabilities. The following chart considers only these
full-blooded, indigenous groups.
