Are the iq fag who constantly posts here?
Nope, merely pointing out that you probably shouldn't rely too strongly on a study with such a counter-intuitive result that hasn't been replicated.
The genetic differences that exist among populations are characterized by gradual changes across geographic regions, not sharp, categorical distinctions.
And orange is on a spectrum between red and yellow, does that mean that "orange" is just an invented category?
Really, that's the blank slateist "rebuttal" to hereditarianism in a nutshell, i.e. splitting hairs and building strawman arguments. Which hereditarian scientist claimed there was a particular gene that every white person, everywhere possessed?
What makes the current study, published in the February issue of the American Journal of Human Genetics, more conclusive is its size. The study is by far the largest, consisting of 3,636 people who all identified themselves as either white, African-American, East Asian or Hispanic. Of these, only five individuals had DNA that matched an ethnic group different than the box they checked at the beginning of the study. That's an error rate of 0.14 percent.
According to Neil Risch, PhD, a UCSF professor who led the study while he was professor of genetics at Stanford, the findings are particularly surprising given that people in both African-American and Hispanic ethnic groups often have a mixed background. "We might expect these individuals to cross several different genetic clusters," Risch said. This is especially true for Hispanics who are often a mix of Native American, white and African-American ancestry. But that's not what the study found. Instead, each self-identified racial/ethnic group clumped into the same genetic cluster.
Ayo hol up, u be sayin dat racial self-identification can be matched with almost perfect accuracy to your genetic profile?
