    Are there any humans who are still thoroughbred? As in, their entire lineage never once bred outside its own DNA?

    Just curious...

    How does one define "within a lineage"? Because we have discovered mitochondrial Eve, and to a large degree, a genetic Adam, that a massive percentage of humanity descended from. Under that discovery, we are all quite literally the same lineage.

    I think royal families stopped inbreeding a long time ago. Or they put a limit on how close within the family tree you could marry.

    Can someone say hemophilia?

    That's only one possible allele that can be concentrated by inbreeding. It's quite the list.

    What about those blue people in the ozarks?

    Or Pacific Islanders ?

    Isolated tribes in the Amazon?

    I read that all caucasians have anywhere from 2-4% neanderthal DNA.icon_biggrin.gif

    More specifically, Western European descent.

    The numbers here are weird. With such a high level of similarity, how much genetic crossover that's present is tough to calculate. It's not surprising though, considering the geographic overlaps at the time.

    Though there is evidence we actually hunted them to extinction, so how much we interbred and why is a big question.

    Well... my parents are first cousins.

    But it's okay because they have their cousins, and then they have their first cousins and then they have their second cousins...

    Don't rate there is such a thing as "through-bred" human. It would be the equivalent of a pure breed Black, White, Indian... you name it pure-breed. Somewhere down the line they all meet genetically, but certain differences have been kept that are specific to that line only.

    Amongst humans that doesn't generally happen icon_razz.gif. Also you'd need to place a time-frame through which a line must be kept 'pure' to ensure that there are no unwanted dormant traits. That is artificially possible through eugenics....but it's considered unethical.

    The short answer is probably no icon_razz.gif

    I've got no inbreeding in me, and I've got 8 different races running though my bloodline. icon_wink.gif

    I thought eugenics died in the mid-40s.

    If it helps you win the Kentucky derby then by all means!

    Some cultures tend to not "mix" outside of their culture very much and have a rather pure lineage, i.e. people from Iceland and Japan.
