我们所称为遗传漂变的遗传变异的随机损失过程如何？（等等问题都应该予以考虑。）

And what about the process of random loss of genetic variants, which we call genetic drift?

所谓遗传漂变就是指：在一个有限的种群内，由于配子的随机取样使得遗传组成在种群内发生变化的现象。

Genetic drift is change in the genetic composition of a population arising as a consequence of sampling of gametes in a finite population.
