Role of DNA in Ancestral Roots

In its most typical type, genetic genealogy consists of the testing of DNA by individuals and doing traditional research on genealogy in search of lost family members.

The forensic applications of genetic genealogy stemmed from the direct-to-consumer DNA testing craze which took off a decade ago, when businesses like 23andMe and Ancestry offered customers an opportunity to inject their saliva into tubes in order to obtain information on their ethnicity, medical risk as well as family connections.

This same technique can use in a criminal context to match the DNA xet nghiem adn tai ha noi of crime scenes with the profiles of databases that are public, for example, GEDmatch. Close genetic matches will give a good starting point to investigators when they are establishing their family tree.

Y DNA and Paternal Genealogy

Men have a very different DNA from women. Therefore, the Y-DNA test can show their paternal direct lineage that dates back several hundred or thousands of years.

Many companies provide mtDNA testing. For instance, 23andMe and others analyze only the HVR1 or HVR2 regions of mtDNA while others, such as Family Tree DNA, test for the whole mtDNA sequence as well as provide cousin match.

If the match is successful, it can aid investigators in constructing families and determine the individual suspect. The analysis of the themes revealed that participants’ notions of the concept of identity are often challenged due to unexpected results from DNA tests.
