说明
这是2014年由Veritasium发布的一部讲解,主题归在Evolution & genetics。它讲的是x-chromosome inactivation这一支里的具体问题,而不是把整个领域扫一遍。适合按兴趣直接看、不打算先补课的人。内容上可以概括成:Veritasium explains X-chromosome inactivation, where different cells in a woman's body switch off different X chromosomes, giving a mosaic pattern. It uses animation from the WEHI institute and connects to calico cat coloring.这些读者给出的理由,核心是:Commenters point to it as the best short explanation of X inactivation and why calico cats and some human traits are mosaics.讲法不绑某一条新闻,过几年仍然可以当材料看。从2015年到2026年,有2位不同的读者在2个不同月份把它推荐出来,其中明确叫别人去看的有1次。适合用一集把一个概念补上的人。抓住它用的那个图像或类比,比背公式重要。如果已经会了基本定义,就把注意力放在它怎么把x-chromosome inactivation变成能跟着复述的例子。
