Genealogy Ethnic Ancestry Family Tree DNA Test Details
How does the DNA Labs India Ancestry Test differ from other DNA ancestry tests?
Other ancestry DNA tests provide a limited ethnic composition at a regional or country level. For example, they might indicate 33% Asian, 40% sub-Saharan African and 27% European.
DNA Labs India Ancestry Test goes beyond these broad ethnic classifications to identify your ancestral origins to a precise geographic location using an unprecedented number of gene pools and reference populations.

What kind of technology does the DNA Labs India Ancestry Test use?
The DNA Labs India Ancestry Test is an Autosomal DNA test, also known as an SNP (pronounced ‘snip’) test. It extracts markers from your Y-Chromosome DNA, X-chromosome DNA and Mitochondrial DNA
There are four types of DNA:
- Y-DNA, which only occurs on the Y-chromosome, is passed down from father to son through the generations and is only inherited by males.
- X-DNA, which only occurs on the X-chromosome, is inherited by women from both parents, and by men from the mother.
- Mitochondrial DNA(also known as mitochondria or mtDNA) is passed down through the maternal line and is inherited by sons and daughters, but only passed on by females. It is the least changeable type of DNA, found outside the cell nucleus, not on a chromosome.
- Autosomal DNA can be inherited from hundreds of thousands of your ancestors through the ages. Autosomal DNA can be found in 22 chromosomes and provides 90% of your DNA.
The DNA Labs India Ancestry Test DNA test examines nearly 800,000 of your autosomal markers (SNPs) and compares them with the distinctive mutations in the gene pools of 862 reference populations. This pinpoints the places and times where your DNA last changed.
How accurate is the DNA Labs India Ancestry Test?
The accuracy depends on your family history. If your parents are from the same place or two different locations, and not mixed themselves, the test can trace your DNA signature back to the country of origin 90% of the time. The test will predict the correct continent.
In a study of people from across the world DNA Labs India Ancestry Test algorithm predicted continental origins with 98% accuracy, assigned 83% of the individuals to their country of origin, and, where applicable, 66% of them to their regional locations.
If your ancestors were from Western Europe, and your parents came from the same region, not moving far from the place that they came from, the test will place your DNA signature within 50 miles of its true origin, and often closer.
Your results will show the origin as a point on a map. Any expected error appears as a circle around the point – the smaller the circle, the more accurate the result. The accuracy also depends on the size of the reference population in a given area; the larger the reference group, the more accurate the results will be.
Can I increase the accuracy of DNA Labs India Ancestry Test DNA testing?
The accuracy of DNA Labs India Ancestry Test correlates to the number of reference populations we use. Completing the survey below will help us increase the size of our reference database.
The DNA Labs India Ancestry Test DNA test works like a car’s satellite navigation system, using reference points to locate a position. If you add more reference points, the accuracy increases. In the same way, the DNA Labs India Ancestry Test algorithm will improve accuracy with more reference populations. Please participate in our questionnaire as your information will help us in this process. Your answers to the questionnaire will NOT affect your results.

Can I use an existing DNA ancestry test? Do I need to take another one?
DNA Labs India Ancestry Test tool provides the full report of where your DNA began. If your previous DNA test was a Y-chromosome test or Mitochondrial DNA (mtDNA) test, it is not compatible, and you will need to purchase the DNA Labs India Ancestry Test DNA test.
