Are modern DNA tests to be trusted?

I myself knew given the fact my dad has a Cajun and creole background that he’d have a fair share of Indian and Even a little black in him. I grew up hearing that his father was a huge chunk Native American as well as Italian. My mom is Anglo, welsh, Scottish and Irish. But when the tests came back it showed a tiny amount of native dna, no French dna at all but lots of German dna… and despite my dad and aunts saying we had full blooded naive Americans as recently ago as like 4 generations ago, Native American was only like 2 percent total. This is strange, obviously. Has anyone else had questionable dna test results like that? It implies I’m predominantly white yes but there’s a lot more black than I expected, no huge groups but like tiny little drops that piled up, only a small drop of native. Is this to be believed or did I make a mistake having a dna test done around black history month?

Again, has anyone else had unexpected/dubious dna test results?

      that sounds completely as expected though.

      >no French dna at all
      there's a difference between being* Cajun and having a "Cajun and Creole background" If you were more specific that could help explain this confusion.

      the only discrepancy is that many people think "full-blooded indians" were actually full-blooded. they weren't. Indian tribes as a whole carried a significant degree of white admixture if we're going off of the late 1800s.

        1. I suppose it would. Again we assume native Americans by the later 1800s were still predominantly native by ancestory and this really isn’t the case.
        2. Very true, as that could just mean you’re around the area and over time your family fully integrated into that culture.

        So for all I know some “native Americans “ my ancestors got with were only slightly less white than their white partners.

          If you're 2% indian from a great-great grandparent, they could very well be 3/4 indian.
          If you had multiple Indian great-great grandparents maybe they were 1/2 indian.
          One thing to note is that you do not receive genes 50/50 between a parental pairing. you could receive 75/25, for example. Not even bullshitting.

            Also this, children don't always get an exact even split of genes from their parents

      I actually think it may have been my grandmother or great grandmother. I remember hearing some urban tales you could call, regarding I think a possible affair with a Cuban or someone like that with my great grandma on dad’s side. Either that “Cuban” was actually north Italian and that little tidbit got forgotten over time , or the cheating may have actually occurred as recently ago as my grandma’s generation in 1970 (she was born in 1935). I say this because dna tests show the most recent dna you have, right?… well by the looks of it the German and Italian dna is from about dad’s generation. Again maybe I’m incorrect here but idk.

    Modern DNA tests can be very flawed with regards to guessing specific ethnicities within a general region like Europe. To understand why you have to first have an understanding of how “ethnicities” and DNA actually work and the difficulty to establish a clear cutoff point between one and the other.

    That being said, if it says you’re actually 1/4 black then I’ve got some news for you…

      I knew there was black in there but…. Well hell the black is about as centralized as the Holy Roman Empire in 1272AD. Tiny tiny little bits while all the European stuff are huge chunks.

    I’m gonna assume that means my actual ancestors around 1870 MAY have actually only been like 10/5 percent black if that, but due to the restrictive nature of Jim Crow laws and one drop bullshit, they basically got relegated to only being allowed to marry other mixed people. Another reason why I think Jim Crow laws hurt the white stock of the south more than helped it.

    Your ancestors probably weren't full blooded Indians but mixed

    A lot of native american ancestry claims like this are exaggerated or false. Like it's always an indian princess or something. Nobody wants to be descended from Little Running Dog the two-spirit warrior.
    Did you go with Ancestry or 23&Me? The latter is better medical info but the former has a much bigger database for comparison. Other services are fractional compared to them.

    >I HEARD this
    >THEREFORE THE DNA TEST IS WRONG

    and Jessica Alba thought she was majorly non white but turned out to be almost entirely white

    It’s almost like Americans who are so obsessed with “heritage” also make shit up about their heritage. Hence why so many whites claim they have “native” blood. God fordid you’re just English or German.

    They can be trusted in terms of generally mapping out broad areas of ancestry. They’re good at telling you whether you are from the British isles or not, but it won’t be able to tell you with exact certainty how Scottish, English, Welsh you are. Brits very often get bits of Scandinavian dna despite being English for 700 years. It’s because many Scandinavians moved there and there’s a lot of overlap in your dna. However, outside of 23andme which is a scam, it’s not going to give a purely white person bits of native or black dna, or Balkan dna if you’re from nw Europe, etc.
    Another thing to remember is that dna does not pass down evenly between generations. For American mutts like you and I, you may not get as much whatever dna because you only get half of moms dna and half of your dads dna. Your parents in turn get half of their dna from each grandparent. It’s not always passed down evenly. It’s random.
    In your case though, I’m guessing your dad’s family, like so many dumb mutts, overestimated the amount of black and indjun dna. It’s rather rare for a white person to have either, especially Indian. B it whenever there’s a chance to be part injun, they love to larp and pretend without ever doing the groundwork of proving or knowing. It’s an American tale as old as time because many Americans did not take care to carefully and accurately pass down their heritage. It’s why so many Americans believe they’re le epic celtic Catholic Irish even though they don’t have any Catholics Irish ancestors or maybe they have 1 from the 1800s. Unless your dad looks black or native, your family probably made it up or exaggerated the extent of it. You should reliably have more than a smidge of native dna if your dad “had tons.”
    My results have always been accurate and line up with my researched family tree. Your next step is to make a documented and researched family tree—good luck.
