Genetic genealogy is the application of genetics to traditional genealogy. Genetic genealogy involves the use of genealogical DNA testing to determine the level and type of the genetic relationship between individuals.
I am seriously thinking of doing the DNA testing from Ancestry.com. I am 100% Full Blooded Italian (both sides of family); however, I would like to get a more precise picture of my Italian ethnic breakdown. My God-sister took the test -she is 100% full blooded Italian from Southern Italy area, and her results came back with 89% Greek/Roman ethnicity. Anyone know how accurate this testing is to determining Italian ethnic breakdown?
The percent breakdown can change slightly as more people are tested and therefore the database used to determine and describe results changes. I also understand that the description of ethnic breakdown varies with the company doing the testing, so FamilyTreeDNA and 23andMe might give somewhat different results. I suggest Googling for more information about this. The Legal Genealogist blog has addressed some of this, as has The Genetic Genealogist blog.
What company did your relative use for the test? She can broaden the pool to get more matches and use more analytical tools by uploading autosomal data to GEDmatch.com.
You and your relatives would also find it helpful to get mtDNA tests (both males and females), which provide information about your maternal lines and Y-DNA tests (males only), for information on your paternal lines. The more people in your family that are tested, the more you will learn.
My Godsister (not blooded related to me) used the kit from Ancestry.com for her results.
You mentioned the mtDNA and Y-DNA tests for maternal and paternal lineage information. What happens if there is no longer any known living relatives from paternal side for the Y-DNA testing? Can I still get paternal lineage information performed?
If you are a female, and have a brother, you can get his DNA test. If you have no living male relatives, like me, then we are stuck for now. I have been getting hits from my own Y DNA test, but nothing useful. I think Family Tree DNA is the better, because they have an italian surname project, as well as group projects for people with the same haplotype.
I agree with bottino about FTDNA. That's the company I've used for myself, my husband, and an older cousin who agreed to let me test his Y-DNA, since he's the only one left on my father's paternal line. I don't even really know him, but he's my dad's first cousin (my dad is deceased), and another cousin asked him on my behalf, since I'm working on the family history. I chose FTDNA because it has the largest database, does a variety of tests, has good resources online, and has the geographic and name projects mentioned. Those projects used to offer discounts for the tests, but when I looked for that for someone recently, I didn't notice a price difference.
@Bottino and Lesley-thank you both for invaluable Y-DNA info. From what I am aware, I also have no living male relatives from my dad's side. Only two aunts and female cousins. Seems both of you feel FTDNA is the best company to ultimately go with due to their extensive database.
Thanks again for great info. and resource recommendations. Joy.
I just heard that Ancestry DNA has stopped all DNA work. They also bought a database from another source and were not sharing it. FTDNA is still the best overall. I'm getting lots of matches, but none very interesting yet, but there are not a lot of Italians in there. My friend is going back to my ancestral village in Italy in Oct. He will take a FTDNA test kit, and get another Bottino there to do it. I will pay for it, because I am curious as to how similar he might be to me. FTDNA also has several Italian sub groups and a Surname project. It will be more useful as time goes on.
I did the Ancestry test, I'm not 100% loving it though... I got a lot of low matches, I know it all depends on who else does the test. I uploaded it to GEDMatch, but I don't understand how that site works, & yes, I've read/re-read all the help info there. I just haven't had a lot of time to figure it out, I guess I thought it would be easier... Oh well... I'll figure it out eventually!!!
