- A species may be defined as a group of organisms of interbreeding natural populations that are reproductively isolated from other groups and that share in common gene pools. 物种是生物界发展的连续性与间断性统一的基本间断形式；在有性生物物种呈现为统一的繁殖群体，由占有一定空间，具有实际或潜在繁殖能力的种群所组成，而且与其他这样的群体在生殖上是隔离的。

- This attitude is distinctly unhealthy for the gene pool as a whole. 这对于完整的基因库完全是一种不健康的态度。
- This allele is common to many Chinese high-yielding rice varieties and likely represents a relatively recent introduction into the cultivated rice gene pool. 这个等位基因在许多中国高产水稻品种中很常见，并很可能代表着一个相对较新引入栽培稻的基因库。
- Small changes in the gene pool of a population may actually initiate a flush. 在种群的基因库中，微小的改变均可实际地诱发一次种群暴长。
- But some of his attempts to widen the gene pool have proved disastrous. 但是其扩大基因库的一些努力也已经证明是相当糟糕的。
- And it requires stress tests to weed weak nerved dogs out of the gene pool. 故此需要有应激压力测试，以便从基因库中剔除弱神经型的犬只。
- But seed orchards are difficult to control, because tree pollen spreads so far that alien, non-elite trees almost inevitably muddy the gene pool. 但是有种子的果树很难控制，因为花粉传播的太远了，一些其它种类的树木就会不可避免地弄乱此基因库。
- But the one-pound pygmies couldn't make healthy babies, so Idaho relatives were imported to broaden the gene pool. 但是,一磅重的侏儒兔没法产下健康的小兔子,所以爱达荷州同属兔子被引进以扩大基因库。
- Mr Moller claims this is the only way to eliminate aggressive traits from the doggy gene pool. 莫勒先生认为这是从狗基因库中消除侵略性特质的唯一方法。
- It's a rich venue, because Icelanders have a limited gene pool and highly detailed genealogical records. 冰岛居民具有一个有限的基因库和非常详细的人口档案，这使得冰岛成为一个基因宝藏。
- But seed orchards are difficult to control,because tree pollen spreads so far that alien,non-elite trees almost inevitably muddy the gene pool. 但是有种子的果树很难控制，因为花粉传播的太远了，一些其它种类的树木就会不可避免地弄乱此基因库。
- Tibet is one of the most typically biodiverse regions in the world. It is an important gene pool for the biodiversity of the globe. 西藏是世界上生物多样性最典型的地区之一，是保障地球生物多样性的重要基因库。
- Admittedly, already, through our own genotypes, and by our choice of mate, we limit the gene pool available to each child. 不可否认，由于我们自身的基因类型和我们对配偶的选择，我们已经限制了每一个孩子可获得的基因库。
- Nature has provided all of its creatures with competitive factors that give them the ability to compete and survive in order to pass on the gene pool. 大自然所有的动物提供了有竞争力的因素,使他们在竞争和生存的基因库,以期通过。
- Knowledge without common sense counts for little. 光有学问而无常识，则这种学问无甚价值。
- Admittedly, already, through our own genotypes, and by our choice of a mate, we limit the gene pool available to each child. 应当承认,我们自身的基因类型以及我们对配偶的选择已经使我们限制了每个孩子可获得的基因库。
- I wanted to find a way to break the cycle and began to look at experimenting with outcrossing to a new bloodline to give our domestic gene pool a chance to refresh itself. 我想要找一种打破这种循环的方法，我开始着眼于通过异型杂交而产生一种新的血统的实验，从而给我们这个大家庭的基因库一次更新它们自己的机会。
- Because identical twins share the same genes and fraternal twins do not, the researchers could identify common genes that result in certain personality traits and predispose people to happiness. 由于同卵双生的双胞胎基因完全相同，而异卵双胞胎不完全相同，所以研究人员可以分辨出决定某些性格特征及使人容易快乐的共同基因。
