当生物学家说人和黑猩猩是由共同祖先进化来的时，他们的意思是，自从二者分野后，这两个隔离的种群都发生了延续性的可遗传变化。
When biologists say that humans and chimps have evolved from a common ancestor they mean that there have been successive heritable changes in the two separated populations since they became isolate.
这对于理解遗传变异性的空间变异、理解岛屿种群和其它隔离种群的保护问题有重要启示。
This has implications for our understanding of spatial variation in genetic variability and for problems of conservation on islands and in other isolated populations.
选择患者亲属做对照、基因组对照和选择遗传背景较为一致的隔离人群都可以减少混杂。
It could be reduced by selecting relatives of affected patients as control, genome control and by using isolated populations which have higher homogeneity in genetic background.
通过遗传算法搜索出隔离系统中最佳的作用力使得此隔离系统的性能达到其极限，即在受到冲击时位移响应最小。
The best power that makes isolation system's performance reach limit is got through GA. The extreme response displacement of the system is minimum when system is impacted.
将增量模态叠加法和伪并行改进遗传算法相结合，解决了冲击隔离系统限位器参数的优化问题，这对于冲击隔离系统的优化设计具有重要的实际意义。
IMSP and PPIGA have been combined to solve the optimization problem of the displacement restrictor parameters, which is significant for the optimization design of the shock isolation system.
本文采用AFLP分子标记，以来自同一母体种群并在5种寄主植物上隔离饲养21个月、29个月和36个月的烟粉虱种群为样本，分析不同寄主和不同饲养时间样本的遗传变异。
The AFLP marker was used to analyse the genetic variation among different samples which were rearing 21 months, 29 months and 36 months separately collected from 5 host plants.
