In mammals and in birds, the sex of an individual is determined by its genes. A sex determining gene on a sex chromosome influence the development of ovaries or testes. But sex in fishes is much more diverse! What controls sex development in fish? Sex genes like in mammals and birds? Or do other types of sex determination systems exist in fish? In this short scientific graphic novel, Sophia Breslin , John Postlethwait , and Thomas Desvignes introduce you to the control of sex determination in fish: from the genetic regulation by sex determining genes and sex chromosomes to various cases of hermaphrodism and the influence of the environment, revealing the myriad of different sex determination systems found in fishes.
