Is it possible to find out what nationalities genes are present in any person by doing genes tests?

Question

I think that regardless all the possible nationalities blended in one person only one nationality type is dominant.

Answer 1

No. The genetic testing that's available today tests for deep ancestry and can point you to the right region perhaps via ancient migration patterns, but it is far to ancient to be considered a "nationality" indicator. And nationality today (and in the last 400-500 years or so) is very transient since travel technology has had significant changes to our migration patterns (you don't inherit your parents nationality).

Answer 2

Nationhood is a fairly recent occurrence, but I believe they will be able to trace it back to a specific area, sometimes, a specific country. The tests I saw them run (I saw this on PBS television a couple years ago, when they ran the tests on 12 black americans and traced their lineage) gave percentages. It showed where most of your lineage was from, but also included the lesser amounts, so you will get a pretty good idea of where your ancestors are from. Here are some sites that offer the tests and some further information:

Answer 3

No.

Answer 4

Not at present, No.  

Most of your DNA is Autosomal which you get 50-50 from both parents coming down from all your ancestors.  It determines things about you like your pigmentation, eye color, bone structure, height etc.  However using Autosomal is very complicated. DNA testing companies are working on ways to improve on it and make it more accurate.  

Autosomal is the only DNA that relates a female to her father or anyone to all the lines that have married into their direct Y & Mitochondrial lines.

Y DNA is passed from father to son only.

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

Y & Mitochondrial are a very small part of your ancestry.

As you go back the number of people you are directly descended from pyramids.  Example: If you get back to your 6xgreat grandparents, barring any duplicates, you are directly descended from 510 individuals.  Of those 510 individuals, you get your Mitochondrial DNA from only 8 and if you are a male you get your Y DNA from only 8. That leaves out 494 people just by getting back to your 6 x great grandparents,  The widening will double each generation you go back.

Y & Mitochondrial can be a valuable tool in matching your family tree to another and if you can do this you will very likely discover spouses and the different families that married into your direct Y & Mitochondrial lines.

They will assign you to a haplogroup for both the Y & Mitochondrial lines which will show you the migration pattern of your ancestors back thousands of years but only for those 2 lines.

You have to understand, there are no pure nationalities, or pure races or ethnicities.  The same DNA crosses national, racial or ethnic boundaries.  People within national, racial or ethnic boundaries will have some different DNA that other within their group.

So, if they can identify your group it would be something like Northern European etc, but nothing more specific.

I think DNA testing companies are misleading people, maybe not intentionally, in stating they can get your deep ancestral roots.  They should emphasize you can get your deep ancestral roots ONLY in your Y & Mitochondrial lines.

Answer 5

IT is indeed possible to determine what are of the world you may have come from based on genetic testing.

As a nurse, i can certainly attest to the fact that dna testing has come a long way.

" Both men and women can be tested to see where their own mitochondrial DNA will compare with the CRS, or the Cambridge Reference Sequence, which is the first DNA of this type tested and is now used as the baseline comparison for all others.

By comparison to this DNA, you will perhaps come to know more about your mother, grandmother or great grandmother, including what nationality she was, and from where she originated.'

If you're interested in learning a bit more about your ancestry, there is a great site that has some good articles, and you might also try rootsweb or ancestry.com

Answer 6

I can give you two examples of different nationalities:

My husband tested his DNA because we couldn't get past his grgrgrandfather.  The test is from father to father, etc. We matched 3 other lines with his last name and we found that although it is assumed this is a Welch name, he's actually Irish.  HIs Halo group (a part of the testing) showed this result.

I just got my DNA back today. It's from mother to mother, etc. I am from the group K which comes from 20,000 years ago and shows I am decended  from one if the 7 daughters of Eve.  It also told me this group migrated mostly from the northern Italy area.

So if you test you get your DNA  origins of nationality.  Not to mention you might match others who have similar DNA sequences.

Answer 7

No.  Your nationality is that of whatever country you are born and raised in.  It is not something that is in your DNA and you do not inherit it.  If your ancestors for the last 1000 years were Italian, but your parents moved to France before you were born, and then you were born in France, then your nationality is French, but you have Italian heritage.

As far as DNA test showing what countries your ancestors were from?  Not exactly.  They can show regions of the world, but as far as countries go, well the borders and names of countries change over time.  Even within my own lifetime, some countries have ceased to exist and others were formed, and borders were changed.  When I was born, there was an East and West Germany.  Now it is just one Germany.  When I was born, there was a Yugoslavia.  Now, that country does not exist, and in its region are 5 new countries.  When I was born, there was the USSR.  That no longer exists and there are now 15 separate countries in its place.  But in each of these cases, the land is still there, the people are still there.  Only the borders have changed, the names have changed, the laws have changed.  Therefore, the nationality has changed.  So it is impossible to tell nationality based on DNA.  Only geographical regions.

Answer 8

When identical twins are born, their DNA is almost 100% the same. As the twins age, their DNA becomes more and more different. DNA is affected mostly by radiation. Radiation is present in rocks, soil, water, and comes zinging at you through the air.  Radiation causes mutations, or changes in the DNA molecules.

It is these changes that allow DNA to be used to trace human migration patterns; and to allow specialists to tell you where your ancestors came from. The mtDNA tells where your mother, her mother, her mother, etc., all the way back in time, came from. The yDNA tells where your father, his father, his father, etc., all the way back in time came from.

So, yes/no to your question. DNA allows geneticists to tell where in the world (countries) your ancestors came from. You must remember that the U.S. is an older country than Germany or France. The U.K. used to be Britain; before that it was England. (Yes, there is a difference.) That is why, usually, when you have a DNA test done, they ask where your ancestors came from in terms of cities.  E.g., Strassburg, now in France, has been in Germany so many times that DNA from there would have to, by necessity, reflect both Germans and French.

I would recommend www.familytreedna.com, not only because it is the site that I used but because it is one of the oldest and best. They also do DNA testing for the National Geographics Genotype Program (which traces human migration pattersn worldwide). Mine revealed that I have ancestors from several tribes of Native Americans, Innuits, Eskimos, all over Europe, parts of the Middle East, more than 20 countries in Africa, China, Japan, Viet Nam, the Philippines, Australia, New Zealand, et al.

So, in regards to your "I think that regardless all the possible nationalities blended in one person only one natinality type is dominant", you can see that, first of all, you mean country of origin (my wife and sons have dual citizenship, but presently it is impossible to have citizenship --- your nationalities --- from hundreds of countries; and, secondly, as DNA is constantly changing, being constantly mixed with other races/groups, there just is no way for one origin to be dominant.

I not only recommend that you go to the above-referenced website to read what they say but to also read some books on the subject, such as:

“Mapping Human History: Discovering the Past Through Our Genes” by Steve Olson

"Genealogy 101" by Barbara Renick and

"Trace Your Roots with DNA: Using Genetic Tests to Explore Your Family Tree" by Megan Smolenyak Smolenyak and Ann Turner.

Answer 9

based on some of the newest dna labs, dna testing can determine which areas of the world your ancesters migrted to from africa from which we all came
