然后我们才能真正地开始寻找该物种的种内遗传变异，并获得和耐药性或毒力有关的一些基因的信息。

Then we can really start to look at the genetic variation within the species and gain insight into some of the genes involved in drug resistance or virulence.

体细胞无性系变异已获得一些作物专利，并以此作为一种手段来产生可供选择的遗传变异，且假定该作物一旦移植生长，它的基因稳定。

Somaclonal variation has been patented in some crops as a means of producing genetic variability for selection, and it was assumed that the crops were genetically stable once established.

现在，25 %的对疾病的敏感性被归咎于遗传变异。但在镰细胞基因上的变异仅仅参与了其中的一小部分。

It is now known that genetic variability accounts for 25% of susceptibility to the disease, but that variations in the sickle-cell gene contribute to only a fraction of that.
