genetic variation

基本解释

Each group carried only a subset of the genetic variation from its ancestral population.
每个族群只携带有他们祖先群体中遗传变异的一部分。
Indeed, one of the great surprises of the past decades has been how much genetic variation there is, for there’s far more than anyone expected.
事实上，过去几十年来人们一直对有多少种遗传变异争论不休，因为这个数字远远超出任何人的想象。
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.
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。

Again,where I think there is at least a moderate impact from genetic variation."
are very similar genetically. "And that's a real problem when you're trying to overcome new insect or disease threats or pressures, or trying to breed a plant that's more water efficient, or even finding genetic variation for water production."

He says that he and others working the field expected to find a pretty big amount of genetic variation.
