Is there any possible way for humans to find out their ancestry through blood tests?

Answer 1

Blood test are not used. They use DNA test which frequently just requires a swab of the mouth.

However, that is an expensive way to start of. You need to get as much information from family as possible. Go to your local library and check the genealogy section. They might have a subscription to Ancestry.Com which has all the censuses through 1930. The 1940 is not available for the public yet. Censuses shows place of birth of everyone enumerated.

Call your nearest Mormon Church and find out if they have a Family History Center and if so the hours they are open for the public. They have records on people all over the world and are very helpful. Most of the people availing themselves of their resources will not be Mormon. They won't bother you with religion.

While you are at the genealogy section of your library and the Family History Center, you most likely will make contact with people who can give you a lot of advice.

Maybe, later you would want to have a DNA test done.

Y dna is passed from father to son only

Mitchondrial DNA is passed through the female line. Sons get mitochondrial from their mothers but they don't pass it on to their children. So the mitochondrial is good to trace from grandmother to mother to daughter etc.

Autosomol DNA is what most of our DNA is made of. We get 50-50 from both parents. Right now the only thing they use it for is to determine the paternity of a female and for racial and ethnic heritage. It will cost you from about $250 to $300.

Answer 2

If your dad is one of three possible men, yes, a blood test can eliminate some of the possibilities.

You probably meant a DNA test. It can tell you if you have native American or African American "Markers". If you are male, they can compare your DNA to other males. (They use the Y chromosome.) If you match on 12 points, there is a 90% chance you and the other man have a common ancestor less than 600 years ago. If you match on 37 points, the odds go up and the years come down. (But the tests cost roughly $125 per 12 points.) That still won't tell you that your 14th great grandfather was Yoric the Red of Swansdown, but it is kind of interesting.

Note that it depends on there being at least one other, and preferably many other DNA samples, from males with your surname in the testing data base.

DNA Testing comes in handy when, as in my case, three fellows with the same surname show up in 1720 - 1740, six ridges west of civilization in what is now WV & Kentucky. They start stealing land from the Indians, keeping slaves and making their own whiskey. They don't tell anyone why they came there, where they came from or how many jealous husbands were looking for them. We suspect they were related. DNA tests show we 7th great grandsons match on 34 out of 37 points, so they probably were related, and their mutual father - or grandfather - was probably the George Pack in Maryland who died in 1754.

Answer 3

Blood test are samples taken at birth or at a later stage. Each and everyone of us has blood and that blood has types and those types have groups and those groups have sub-groupings etc, etc. In finding relatives using actual blood is not done per say. Many years ago people who disputed relatives were subjected to blood tests, if the outcome was the same or identical, the law stated that the relatives were linked. Thats all that could happen. Nowadays they use DNA testing...though at a very early stage. Blood is important and keeping it in the person is more important at this time.

Answer 4

Interesting question. Maybe these tests have been done but no correlation between IQ and bloodtype have been found. But there is strong evidence that Ashkenazi Jews specifically score significantly higher than other ethnic groups in aptitude tests and have a disproportionate amount of Nobel prize winners among them. I am not sure where, but I've read somewhere that they also have rarer bloodtypes. Whether that has anything to do with aptitude I don't know.

Answer 5

Using DNA is the most accurate way to check your ancestry. The thing is, though, it will not give you names and dates, occupations, all the fun stuff of genealogy.
There are so many websites for tracing ancestry through DNA, such as www.familytreedna.com or www.africanancestry.com. Fortune magazine mentioned www.23andme.com, but I got no where with the last one.
I did use familytreedna, and I like the results. They send a kit with 2 swabs in it; you rub the inside of your cheeks, send the kit back and they will send you a report of your ancestry, plus they have a webpage of your own listing people with close matches.
Through this, I have learned that my ancestors (one test for yDNA, one for mtDNA) came from every European country, several in Africa, Canary Islands, Channel Islands, Iceland, Isle of Man, Carribean Islands, Mexico, Central and South America, American Indians, Inuits, Eskimos, Pacific Islanders, Asian countries, mid-east countries...
DNA for each color (red, yellow, black, brown and white) is different; it is also different for each tribe or ethnic group, so, what are you waiting for?

Answer 6

Not blood tests, but DNA tests (you don't need blood, any body fluid has your DNA. Most commercial tests have you swab the inside of your cheek.)

Three available tests can tell you three different things which can tell you something about your ancestry: (1) admixture can tell you the percentage of the four gross phenotypes ("races") you are; (2) mitrochondria DNA traces your mother's mother's, ad. inf. line; (3) Y-chromosome (if you're a male) traces your father's father, ad inf. line.

None of these tests really establishes your ancestry, in that none can pin down specifics, and none are replacements for actual research, but used wisely, they have merit in geneaological studies. I view them as a tool to complement (not supplement) documentary research - to place male lines of unknown lineage, establish intermarriage, etc.

Answer 7

Guess what........through blood tests, all they can say about your ancestry is that you are a Homo Sapien out of Africa. Wouldn't it be nice if all the governments in the world realized that we are all the same, independent of any country?

Answer 8

dnd is the way, but would cost.
program on bbc last week or so followed mum & daughter people of a village where they had family with same names were test & results were mixed.
of people test 3 found that they were family but before did not know
