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 where that person comes from, provided that its parents or grandparents haven't moved around too much.
Y dado que hay muchas variantes genéticas y tienen diferentes gradientes, esto significa que si determinamos una secuencia de ADN, un genoma individual, podemos estimar con bastante precisión de dónde viene una persona dado que sus padres o abuelos no se han movido demasiado.
