Rasliga grupperingar
matchar genetiska profiler

Inom den moderna politiska sfären har det i samband med den globaliserade mångkulturen blivit omåttligt populärt att hävda att raser inte existerar, och att begreppet "ras" vilar på rasistiska och socialt konstruerade grunder. Verkligheten är, som vanligt, en helt annan:

Checking a box next to a racial/ethnic category gives several pieces of information about people - the continent where their ancestors were born, the possible color of their skin and perhaps something about their risk of different diseases. But a new study by researchers at the Stanford University School of Medicine finds that the checked box also says something about a person's genetic background.

This work comes on the heels of several contradictory studies about the genetic basis of race. Some found that race is a social construct with no genetic basis while others suggested that clear genetic differences exist between people of different races.

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. 1

Vad spelar det för roll om indelningen i raser är en social konstruktion, så länge den överensstämmer med hur de etniska skillnaderna fungerar och ser ut i verkligheten?
