Understanding evidence for the genetic basis of reproductive isolation is imperative for supporting students' understanding of mechanisms of speciation in courses such as Genetics and Evolutionary Biology. An article by Andrés et al. in the February 2013 issue of GENETICS illustrates how advances in DNA sequencing are accelerating studies of population genetics in species with limited genetic and genomic resources. Andrés et al. use the latest sequencing technologies to systematically identify and characterize sites in the DNA that vary within, and have diverged between, species to explore speciation in crickets. This primer, coupled with that article, will help instructors introduce and reinforce important concepts in genetics and evolution while simultaneously introducing modern methodology in the undergraduate classroom.

理解生殖隔离的遗传基础的证据对于支持学生在遗传学和进化生物学等课程中理解物种形成的机制至关重要。安德里斯等人在 2013 年 2 月的《遗传学》杂志上发表的一篇文章说明了 DNA 测序技术的进步如何加速了具有有限遗传和基因组资源的物种的群体遗传学研究。安德里斯等人使用最新的测序技术系统地识别和描述 DNA 中在物种内和物种之间发生变异的位点，以探索蟋蟀的物种形成。这篇入门读物，加上那篇文章，将帮助教师在本科课堂中引入和强化遗传学和进化中的重要概念，同时引入现代方法。遗传学相关文章：安德里斯，J.
