My whole class took a geneolgy test !! for <race> origin etc ...?

Question

We noticed all the African americans and Biracial african ameriacans had 25-50% sub saharan African ancestores and 30-60 percent caucasion anscestores 20-40 native American ancestres the spectrum was astaunishing one girl thought she was full black and shes only had 20 percent African gentics and 40 percent white 40 percent Native American...







The funny thing was 6 out of the 8 white children had 7-11 percent west african or sub saharan african ancestory and they didnt want to beleive it some though tit was cool some said they didnt believe it others said the test was a crock ! Theres was only one full caucasion because shes straight out of Russia no American mixing ! There was white girl who had 10 percent east asian ..



Now what I dont understan is how do all these whites kids in my class have black ancestores one girl was 20 percent subsaharan African and she was shoked the Ironic thing is some black were around 20 percent so we found that to be kinda funny...

Do you think

These test were inaccurate how do all these whites have black in them its o weird !! Our teacher said hey if it was 1700 all the whites in hear but 2 would have been considered black and would have been slaves ...

Where these test wrong

How can all the whites have black blood in them !

The test said 99.99 percent correct do you believe they are ..

Answer 1

I find a racial mixed ancestry of both the African-American and the European-American students believable, although the percentage is perhaps a little high since Wikipedia lists the percent of white Americans with African blood at 12.90 percent..

http://en.wikipedia.org/wiki/List_of_African_subcultures).

Similarly another web site notes, "70 percent of whites have no African Ancestors. Among the 30 percent who do, the black admixture is around 2.3 percent, which would be like having three black ancestors of out 128." However, according to the same web site there is a "17 to 18 percent white ancestry among African-Americans, the equivalent of 106 of your ancestors from seven generations ago having been African and 22 European."

After all, the story of Sally Hemmings and Thomas Jefferson is pretty well established, and more than a few whites also have forebearers of Native American ancestry. If the descendants of such unions could pass for "white", they almost always did so.

But considering that the price of each DNA test runs around $350, I find it highly unlikely that a public school would underwrite the cost of the testing!

Answer 2

Your question has nothing to do with God, so I'll just leave him out of this. So, magic or QCD phase transition? Well, since 'magic' means that stuff we don't understand caused something to happen, obviously magic is the most correct answer. It also isn't an answer at all--which is why it is good that people are exploring other ideas for the origin of matter. Your link wasn't very conclusive, but looks like a thought in the right direction. By the way, do you think that thoughts are real? I find that people looking at a tiny corner of 'magic' often forget how much of it is out there. A lot of people think that explaining a miracle makes it less miraculous, while I'd strongly disagree. My studies have been more focused on biology than physics, and the more I see how things happen, the more miraculous they seem. Getting rid of the magic doesn't get rid of the miracle--it just tells you how it was done, like one of those TV shows exposing an illusionist's secrets. It doesn't make the illusion less entertaining--you already knew it was an illusion before you saw it--explaining how or remaining baffled doesn't make it 'fake' or 'real'.

Answer 3

Bizarre. Did you make this whole thing up? There's surely no such thing as a "genealogy test" or someone -- no, all -- would have learned some genealogy, which is the research and documentation of dead ancestors. Genealogy just isn't magical.

Now, we did have one of my brothers do the yDNA surname research test, I think it put us into R1b.

I can't imagine school taxpayers funding thousands of dollars for DNA testing on any level, then allowing an ignorant teacher to tell a class of youngsters their ancestors would necessarily have been someones' slaves. On another hand, you do know that humans evolved in Africa, but that's paleontology or physical anthropology.

DPOMLATMIR thank you Judge Judy.

Answer 4

Yes I do believe it. Peter Jennings did a special on all the different races. In it he said there was a lot of mixing. I can't remember all the details but I do remember he said that white men owned female slaves and the men would rape them. So now you have a baby with both races in his blood. He or she grows up, has a baby and passes his or her blood to that baby and so on. Which means although we consider ourselves white or black (whichever the case may be) chances are very good that we have some of the other race in us. Also there are many many types of races.

Answer 5

Technically we all come from Africa 10's of thousands of years ago each "race developed as it left from africa and migrated to its place of origins and developed its own genetic markers. My own family has been in america well over 250 years and yes some owned slave and yes I've had my y-dna tested and I only had 1 hit for Africa as everyone does and thats for my prehistoric grandfather that developed on the African plains. and it certian never told me what percentage my DNA was for each group i matched It just told Me I belong to a race of people that left Africa between 20,000 and 60,000 years ago settled first in the moutians of present day Iran then moved to the present day Balkans region then into present day Denmark and Northern Germany and eventually settled in Scotland and England. I'm not sure of your test I've never heard of percentage in DNA unless testing paternity for a father to see if the baby is his.

Answer 6

Well,I'm Polish and my family is mostly Slavic and we mostly have ancestors from the Ukraine about 2000 years ago due to anthropologic studies. It is completely logical that whites can have black ancestors. People dont just stay in one place, people around the world emigrate and migrate.

Answer 7

I don't know, I'd probably have to take the test myself to find out if it is wrong or not. Since my great-grandparents were full-blood germans (came from Germany) and the other great-grandparents were full-blood norwegians,(did come from Norway) and my mum is full-blood filipino.(from the Philippines) If it said I was black or indian or something other than what I am, I know it would be wrong.
Plus both of my great-grandparents came to the U.S. when no one owned slaves anymore. So they didn't have slaves and indians were away on reservations.

Answer 8

Yes, there was more race mixing in the past than people like to think. Because of the prejudice against blacks anyone who looked white tried to "pass" as white.
Of the decedents of Thomas Jefferson and his slave mistress Sally Hemming, about half are living as "white" and half are living as "black"

Answer 9

Autosomal DNA is used to determine origins of people as well as paternity for a girl.

I feel if your school did this, they are intruding and getting too personal. . They should stay out of things like that. The autosomal DNA test is very expensive. I can't believe a school would spend that kind of money.

Answer 10

Yes, those test are pretty accurate. Forensic scientist can tell what race a pile of bones come from because there are slight differences in each race. If a forensic scientist knows that from the bones, I don't see why a test can't tell where your ancestors come from.
