Which dna tests would be best and can you recommend a reputable company? (1 test for me&1 for my grandfather)?
My grandfather is still alive. He is African-American. I would like to get as much information as I can about my ancestry/his ancestry while he is alive. What type of test/kit do you recommend that I buy and which company should I go through, a reputable one that is? I saw African- America Lives and I see some links on the pbs site, but there are so many different types of tests that it is confusing.
I would also like to have proof that we have Native American blood.
I would not mind taking my own test as well to see where all of my ancestors come from(on both my mother and father’s side of the family) no matter where they are from? Can these test even pinpoint the countries? Thank you.
It is according to your objective.
you are involved in genealogy, and if you want to have your Y & Mitochondrial tested to see if you match with someone else’s family tree, I believe the best is
http://www.familytreedna.com/Default.asp…
They are the oldest company doing this type of testing and has the largest database.
When you go into their website, if you go under “feedback” you can email them and ask questions.
Now, they will assign you to a Haplogroup and show you the origin of your nomadic ancestor going back usually over 100,000 years which I don’t think is particularly helpful in genealogy. It will be in 2 lines only and you come from a vast myriad of family lines. Y goes from father to son only. Mitochondrial goes from mother to both sons and daughters but only the daughters pass it on to their children. One company that only does Y & Mitochondrial advertises they will help you “discover your deep ancestral roots.” Just understand it is your deep ancestral roots in 2 lines. You have 2 parents, 4 grandparents, 8 great grandparents, 16 great great grandparents and so on. You get your Y from only one in each generation and your Mitochondrial from only 1 in each generation. For instance when you get back to your 16 great great grandparents, Y & Mitochondrial both will leave out 14 of them. However, if you are successful at matching yourself with other family trees and making contact with people in those trees, you will no doubt discover some of the left out people.
Your 2 sex chromosomes, one from each parent are the two that are made up of Y & Mitochondrial DNA. They both go back in a straight line virtuallly unchanged.
Most of your DNA is Autosomal. Your other 44 chromsomes, 22 from each parent are made up of your Autosomal DNA. You get it 50-50 from both parents but it is too complicated to use for genealogy purposes. When you get back to your grandparents, it will not be 25-25-25-25 split. You get 50% from your paternal grandparents and 50% from your maternal grandparents but it will not be a even breakdown between grandmother and grandfather on both sides of the family. How you inherited this bias will not necessarily be how your siblings inherited it unless you have an identical twin.
There is one company in the U.S. that I know of that will take your Autosomal and match you with population groups throughout the world. They will not tell you that you are 1/2 of something, 1/4 of something else and 1/4 of another something else. That would be impossible as the same DNA crosses national, racial and ethnic boundaries and there are no pure nationalities, races or ethnicities. However, they will show you your matches in descending order starting with the top. The company that does this type of testing is
http://www.dnatribes.com/
When you go into their website if you go under “feedback” there is a way you can email them and ask questions.
I asked DNATribes if my sister with whom I share both parents had the same Autosomal test would her results be the same and they replied:
“Two siblings will each obtain unique results. Family members do typically share some regional or ethnic genetic affiliations, but in some cases matches can vary substantially between siblings.”
FamilyTreeDNA does do Autosomal testing but they will no longer provide you with an analysis. I had to send my results from them to DNATribes.
Here are a couple of more links explaining DNA
