- What is an mtDNA test? What will it tell me?
An mtDNA test looks at your female-inherited mitochondrial DNA. Because mtDNA is passed from a mother to her children with no input from any spouses along the way, this test will look at your direct maternal line only. You can view an illustration here: http://www.familytreedna.com/inheritance-chart.aspx. The mtDNA tests provide information regarding the single origin of your direct maternal line.
- Should I order the mtDNA HVR2 refinement test?
The mtDNA Refine test allows us to look for high resolution matches with other individuals, who would be the people in the database who are most likely to share a common ancestor with you in a genealogical time frame. It will usually also reduce the least likely matches that you have in the database. If you have many HVR1 matches usually the upgrade is a good idea.
- What will the mtDNA Full Sequence test tell me? There are several reasons that a person might wish to test the full mitochondrial DNA sequence. - to determine the most extended haplogroup assignment according to currently published research, including the ability to refine the haplogroup assignment further as more research is published without the need for further testing. - to identify whether a relationship is likely to be close or distant. - to have the full sequence available to compare with research, to include in research, and to eliminate the need to perform additional mtDNA testing on the sample. Not everyone needs the full sequence in order to find out the information they are looking for. However, it has already become the standard test used by researchers studying the mtDNA, and it is only a matter of time before it becomes the standard test for individuals wanting to use their mtDNA results for genealogical purposes.
