Question: DNA test!?!?!?!?
Since I'm a guy, ca the DNA test trace back my mothers ad fathers line!? ThanksWww@QuestionHome@Com


Best Answer - Chosen by Asker:
Yes, you have your father's Y-DNA and your mother's Mtdna!.
A test of your Mtdna will not show any paternal line at all, only your mother, her mother, your great grandmother etc!., etc!.
The test of your Y-DNA (of your father,brother, paternal grandfather, uncle or male cousins) will show your probable "ethnic" ancestry back to when you evolved 10s of thousands of years ago, and will show the various "additions" along the way!.
Below is a reply I have given to a similar previous question, dna cannot tell you which country you originated in, only the probable area, or areas of the world your ancient ancestors passed through during their evolution!.
Human cells contain 23 pairs of chromosomes: 22 pairs of autosomes, and one pair of sex chromosomes!. Females carry a pair of X chromosomes that can swap, or recombine, similar regions of DNA during meiosis!. However, males harbor one X chromosome and one Y chromosome, and significant recombination between these dissimilar sex chromosomes does not occur!. Therefore, the non-recombining region of the Y chromosome (NRY) remains largely unchanged over many generations, directly passed from father to son, son to grandson, and so on, along with genetic variations in the NRY that may be present!. Scientists can use genetic variations, such as single nucleotide polymorphisms (SNPs), on the Y chromosome as markers of human ancestry and migration!.
It is very effective and the best companies will retest until they get a conclusive result!.
If you have, say, just the first 12 markers tested($149 with FTDNA), that will give an indication of where you originated, the more markers you test on, the more information is gained ( for mtdna, your suggested geographic origin and your maternal deep ancestral ethnic origin, $129 with FTDNA) if you test on the maximumum of, say 67 markers ($349 with FTDNA), it is possible then to find a match to someone else carrying your own, or a different surname, and to prove a link where perhaps no "paper trail" exists!. It can therefore pinpoint a place in which your ancestors probably lived in recent history but DNA does not, obviously,
have a surname attached to it, surnames have only been used for around 700 years and of course your DNA originated 10s of thousands of years ago!. You can also have a SNP test which will help show the migratory pattern of your ancient ancestors, having said that, you can join a Surname project (e!.g!. with FTDNA) and receive discounted prices on your tests!.
I recommend that you make yourself aware of the various tests available, and the costs with each testing company!.
Plus, check out what is available to you after you have tested!.
I used Family Tree DNA ,they were the first in the field (founded in 1999), have the largest data base, and do the testing for the National Geographic's Genome project, their "after sales" is excellent and I consider they are the best, but you have to make your own decision on that!.

NOTE :-
If you are female, you only carry your mother's Mtdna, and her mother's Mtdna, and her mother's Mtdna etc!.,etc!.,etc!. and that will show only your mother's lineage (you will pass that Mtdna on to your daughters and sons, but your sons will not pass it on to their children)!. You do not inherit your father's Y-DNA!.
If you are male, you inherit your father's Y-DNA, his father's Y-DNA, his father's Y-DNA, and so on back to your origin!. You also inherit your mother's Mtdna, but you only pass your Y-DNA on to your sons!.Www@QuestionHome@Com

Y DNA is passed from father to son!.

Mitochondrial DNA is passed from mother to both sons and daughters but only the daughters pass it on to their children!.!.

Most of your DNA is autosomal!. You get it 50-50 from both parents!.

Y & mitochondrial are used because it goes back in a straight line!. However, if you get back to you 6xgreat grandparents, you are directly descended from 510 people, if there are no duplicates!.

Your Y DNA would only come from 8 of those people and your mitochondrial DNA would only come from 8 of those people!. However, you share autosomal DNA with all 510!.

Y and mitochondrial is used in genealogy testing sites as it goes back in a straight line!. Autosomal is more complicated!.

For your Y there might be a surname project that you can compare with others of your surname!. Just put your surname and YDNA in your search engine and see what you come up with!.

Test can be expense!. SMGF does them for free but it will take about 6 months before they have the results!. They won't send you a report but will have it online, but you probably can't interpret it!. They have contracted with GeneTree to interpret the results!. My mitochondrial only cost $19!.50!.

If there are other contributors with your DNA with zero, one and two differences, they will show you their trees!.Www@QuestionHome@Com

A DNA test can tell with a high degree of accuracy whether your mom and dad are indeed your parents, but that's only because you'd compare your DNA to theirs!. It can't trace anything back, it can just compare!.

It's very expensive for a paternity test, $100 and up!. Google "DNA test" to find out!.Www@QuestionHome@Com
