Abstract

On the Black Swans of conventional sex determination theory: There aren't many, but when an exception to the standard model of sex determination (evolutionary turnover of genes playing the role of "master sex determiner") arises, it certainly screams out for an explanation. In this issue, a novel one is put forward. It now awaits testing, particularly at the population level.

摘要

关于传统性别决定理论中的“黑天鹅”现象：这种现象并不多见，但当性别决定的标准模型（基因在性别决定中起“主控性别决定因子”作用的进化更替）出现例外时，肯定需要一个解释。在本期中，提出了一个新的解释。现在需要对其进行检验，特别是在群体水平上。
