Ethnicity Testing
Are you adopted and curious about your heritage?
Are you predominantly African and curious about other ancestry you may have?
Do you want to expand and confirm your family's genealogical studies?
Uncover Your Personal Anthropology!
The AncestryByDNA provides you with a simple and objective description of your ancestral origins. The ethnicity test gives you an estimated percentage of ancestry from the four major historical population groups:
- European: Europeans, Middle Easterners and South Asians from the Indian subcontinent including India , Pakistan and Sri Lanka.
- East Asian: Japanese, Chinese, Mongolian, Koreans, Southeast Asians and Pacific Islanders including peoples native to the Philippines.
- African: Peoples from Sub-Saharan Africa such as Nigeria and Congo region.
"BioGeographical Ancestry admixture" is the heritable component of what we commonly refer to as "race", and AncestryByDNA is a genome-based ethnicity test for determining your BioGeographical Ancestry admixture percentages. The test is the first of its kind ever developed. It reports proportional European, Western sub-Saharan African (African) and East Asian ancestry. For example, one person may obtain a result of 80% European 20% East Asian, while another may type as 33% African, 22% East Asian and 22% European.
Customers recieve their raw genetic data, a bar graph showing the percentages of each group and a specialized representation of their data called a triangle plot, along with a users manual. Ancestry cannot be determined by any genetics test in a black/white litmus test fashion. Instead, the results are reported as statistical estimates, and are qualified with confidence intervals. From over 6,000 tests so far performed, and extensive mathematical simulation, we know that the test is accurate to from 4-8% and sensitive enough to detect, for many customers, a single (100%) African or European great great grandparent, or a single (100%) East Asian great grandparent. Most customers use the test in an attempt to confirm recent admixture events such as this - where the family tree is primarily European for instance but one or more recent ancestors are of other ancestry, East Asian.
The main difference between this test, called an autosomal test, and other genetic tests such as Y-chromosome or mitochondrial (mtDNA) tests is that it surveys across all 23 chromosome pairs, not just one of them. By analogy, AncestryByDNA allows one to read all 23 chapters of their DNA book when inferring their ancestry, not just one of those chapters.

Further information To determine the percentage of DNA a person has from each of these four groups, the test examines 175 Single Nucleotide Polymorphisms (SNPs). These 175 SNPs have been selected based on their bio-geographic polymorphism patterns , and are referred to as Ancestry Informative Markers (AIMs). The alleles found at these marker locations show very high specificity for people from particular populations, ethnicity and/or geographical regions. AncestryByDNA can be used to resolve the following four groups:
- European: Europeans, Middle Easterners and South Asians from the Indian subcontinent including India , Pakistan and Sri Lanka .
- East Asian: Japanese, Chinese, Mongolian, Koreans, Southeast Asians and Pacific Islanders including peoples native to the Philippines .
- African: Peoples from Sub-Saharan Africa such as Nigeria and Congo region.
The Euro-DNA 1.0 Product Upgrade: An ethnicity test to further resolve ones ancestral origin beyond what the AncestryByDNA product does is called the Euro-DNA 1.0. This test is used to further resolve the intra-continental ancestral composition for the European group. To do this, the test examines 320 SNP markers (this is including the 175 AncestryByDNA markers) to look deeper within the following European lineages:
- Northern European subgroup (NOR)
- Southeastern European ( Mediterranean ) subgroup (MED)
- Middle Eastern subgroup (MIDEAS)
- South Asian subgroup (SA)
The Euro-DNA test is only available to participants that test >50% positive for European ancestry using the AncestryByDNA product (then they can purchase the Euro-DNA Upgrade), or if they believe that they have >50% European ancestry and have not yet been tested using the AncestryByDNA product (then they can purchase the Euro-DNA 1.0). If tested using the Euro-DNA 1.0, the results could indicate that someone is 70% Northern European, 17% Middle Eastern and 13% Native American (as seen in the Euro-DNA bar graph on the above right). Human Ancestral Origin™ DNA Migration Patterns (mtDNA haplogroups)
FIGURE 1: This DNA migration pattern map, created from compiled research on DNA populations around the world, demonstrates that the first Humans originated in Africa about 130-180 thousand years ago. Notes: a) mtDNA macro-lineage L is predominant in Africa, b) mt-DNA macro-lineages M and N are found throughout Eurasia and Australia, c) mtDNA lineages H, I , J, K, T, N, U, V, W and X are predominant in West Eurasia, d) mtDNA lineages A, B, C, D, E, F, G, M, P, Q and Z are predominant in Asia and Oceania, and e) mtDNA lineages A, B, C, D, and X are found in the Americas.
