例句

• New versions of a gene can also become universal in a population through a random process known as genetic drift.

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

  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。

• Whether speciation is achieved normally via genetic drift or natural selection is the subject of much ongoing discussion.

  究竟正常的物种形成是通过遗传漂变还是通过自然选择达到的，是现在正在进行热烈讨论的话题。

• But Shoham noticed something strange: Influenza viruses isolated decades apart sometimes showed little sign of genetic drift .

  肖海姆注意到一些奇怪的现象：隔离了几十年的流感病毒有时表现出很少的遗传漂变迹象。

• Do random mutations frequently get passed on or disappear without enhancing or diminishing fitness, a process called genetic drift ?

  随机的突变是否经常遗传给下一代，或者消失，而与生殖成就无关（这个过程叫「遗传漂变」）？

• Much change is due to random genetic drift rather than positive selection. It could be called the survival of the luckiest.

  变化很多是由于随机遗传漂变，而不是积极的选择。这可称之为最幸运者生存。

• This is one form of a process that biologists call genetic drift .

  这是生物学家称之为遗传偏移的一种方式。

  因此近来繁殖问题只选用于遗传漂变。

• Much change is due to random genetic drift rather than positive selection.
