So what this means now is that those traits we then look at and so readily see -- facial features, skin color, hair structure -- are not determined by single genes with big effects, but are determined by many different genetic variants that seem to vary in frequency between different parts of the world.
Tas nozīmē, ka šīs iezīmes, uz ko mēs skatāmies un tik viegli saskatām -- sejas vaibsti, ādas krāsa, matu struktūra -- neietekmē vieni paši gēni ar lielu iedarbību, bet tās ietekmē daudzi dažādi ģenētiskie varianti, kas, šķiet, ka variē biežumā starp dažādām pasaules daļām.
