DNA ancestry tests may help you learn more about yourself and your familial roots. However, you should be skeptical of the results of these tests since DNA testing companies that provide these services use methods that aren’t validated by independent scientists.
DNA ancestry accuracy is determined by the amount of data the test center has accumulated. There is a wide range of DNA sequences. The more DNA sequences there are of individuals from your ethnic group and ancestral geographic range, the better the accuracy rate.
DNA ancestry accuracy is also determined by the degree of intermixture in your lineage. If you come from a heterogeneous background, you may find it more challenging to trace your roots. But if the testing companies have bulk DNA data from these lineages, you may get more accurate results.
DNA tests may be inaccurate due to some of the reasons below:
Companies compare their data from a database that may not produce definitive results. Most DNA testing companies use common genetic variations found in their database as the basis for testing DNA accuracy. Therefore, you may get different results if you use different companies. Some of the ethnicities from Africa, East Asia, South America, and South Asia may be hard to trace because DNA testing companies have limited DNA data in their databases to compare to.
DNA testing companies are selective when it comes to looking for certain genetic variations. These variations account for a small amount of the millions of SNP contained in your DNA.
