中文简介:	遗传学控制着进化。有四种主要的遗传系统，它们是有性/无性和单倍体/二倍体的组合。在所有遗传系统中，适应性遗传变化往往开始缓慢，中间加速，最后缓慢发生。无性单倍体可以变化最快，而性二倍体通常变化最慢。只有人口经过选择，大群体中的基因频率才会发生变化。阅读作业：Stearns，Stephen C.和Rolf Hoekstra。进化：简介，第4章
课程简介:	Genetics controls evolution. There are four major genetic systems, which are combinations of sexual/asexual and haploid/diploid. In all genetic systems, adaptive genetic change tends to start out slow, accelerate in the middle, and occur slowly at the end. Asexual haploids can change the fastest, while sexual diploids usually change the slowest. Gene frequencies in large populations only change if the population undergoes selection.
