X-SV Female Lineage DNA Testing
The X-SV maternal lineage test is used to determine whether two or more people are related through their maternal lineage, or if male and/or female children have the same biological mother. The Mitochondrial DNA sequence variation is passed from females to their children and has a relatively infrequent mutation rate, thus it remains the same through many generations. (Males do not pass the X-SV they inherited from their mother to their children).
This test focuses on the Mitochondrial DNA and results in a unique X-SV profile for each individual tested. It is important to note that this test will not differentiate women that are in the same maternal lineage or children with the same mother.
For example, if a female Child "A" and her alleged half brother Child "B" (Child "B" having a different father than Child "A") want to know if they have the same maternal biological grandmother, and they have the same X-SV profile, it is very likely that they are of the same maternal lineage. If the X-SV profiles do not match, then they neither share the same maternal biological grandmother, nor do they share the same maternal lineage.
This is just one of many circumstances in which the X-SV test can be applied. Review the chart to the right as a guide.
