And since there are many genetic variants, and they have different such gradients, this means that if we determine a DNA sequence -- a genome from one individual -- we can quite accurately estimate provided that its parents or grandparents haven't moved around too much.
少なくとも鳥瞰的に見ると言えます 多様な遺伝上の違いが存在し しかも段階的に違いが広がったということは ある特定の人のゲノムから DNA配列を解析すれば 祖父母や両親が 頻繁に移動しなかった限り 極めて正確に
