Genetic Testing Kits?
♥Shá_Bella asked:
I would like to learn more about my direct genetic ancestry, and I’m looking for a testing kit that can give me a break down in percentages. Can anyone recommend one to me that can trace both maternal and paternal lineages?
I understand that if I want to test both y and mitochondrial DNA, I would need to have a male sibling with the same mother and father to get this done; I plan to do that. I am only looking for a test that will do a percentage breakdown of ethnic background as well, if that’s possible.

Genetic Testing Kit
There are 3 types of DNA
Y which goes from father to son only.
Mitochondrial which goes from mother to both sons and daughters but only the daughters pass it on to their children.
Autosomal which you get 50-50 from both parents but when you get back to your grandparents it will not be 25-25-25-25. You get 50% from your paternal grandparents and 50% from your maternal grandparents but it will not be an even breakdown between grandmother and grandfather in both cases. How you inherited this bias will not necessarily be how your siblings inherited it unless you have an identical twin.
People use Y & Mitochondrial in genealogy as they both go back in a straight line virtually unchanged. However they represent a teeny weeny part of your total ancestry. If a person involved in family history uses them to match themselves with other family trees, they stand a chance of discovering even the left out ancestors. One company that only uses Y & Mitochondrial advertises they will help you “discover your deep ancestral roots.” It is true in those 2 lines only, they will assign you to a Haplogroup based on your DNA and show you the origin of your nomadic ancestor going back thousands of years. But you come from a vast myriad of family lines. You have 2 parents, 4 grandparents, 8 great grandparents, 16 great great grandparents. It doubles up each generation you go back. If you were a male you get your Y from only one person in each generation and if you are male or female you get your Mitochondrial from only one person in each generation. But if you are successful in matching yourself with other family trees along with research, you no doubt will discover some of the left out people. You have to use it in conjunction with family research. Here is a link to a website that does Y & Mitochondrial for this purpose.

Using Autosomal DNA for genealogy is too complicated, at least at present. However, there is one company in the U.S. I know of that will take you Autosomal and match you with population groups throughout the world. They have over 900 batches of 100-150 samples of DNA.
They won’t tell you that you are 1/2 of something, 1/4 of something else and 1/4 of another something else, nor will they break it down in percentages. They can’t do that as the same DNA crosses national, racial and ethnic boundaries. There are no pure nationalities, races or ethnicities.
What they will do is give you your matches starting with the top in descending order. The company is

Most of your DNA is Autosomal. You get 23 chromosomes each from both parents. The two that determine a person’s sex, one from each parent, are the ones made up of Y & Mitochondrial. The other 44, 22 from each parent are made up of your Autosomal DNA. Autosomal is what determines your appearance such as your pigmentation, height, bone structure.
Now, I ask 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.”
I would imagine this is because in the differences of what we inherit from our grandparents.
Also I asked DNATribes if they could break it down between my father and my mother and they replied:
“To isolate each parent’s genetic contribution in each case, it is necessary to test at least one parent as well. ”
Now, FamilyTreeDNA does do Autosomal testing but they will not provide you with any type of analysis. I think at one time they did. I had to send my results from them to DNATribes.
