A ZZ/ZW Sex Chromosome System in Cephalochordate Amphioxus.

Genetics - 1 Mar 2020

Shi Chenggang, Wu Xiaotong, Su Liuru, Shang Chaoqi, Li Xuewen, Wang Yiquan, Li Guang

Abstract excerpt

Sex determination is remarkably variable among animals with examples of environmental sex determination, male heterogametic (XX/XY) and female heterogametic (ZZ/ZW) chromosomal sex determination, and other genetic mechanisms. The cephalochordate amphioxus occupies a key phylogenetic position as a basal chordate and outgroup to vertebrates, but its sex determination mechanism is unknown. During the course of...
