Neth J Zool — Sex ratio shifts only occur at extreme temperatures, and thus represent thermal effects on GSD a, b. In addition, a significant increase in amh expression is observed in putative males at MPT and at MixPT approximately one week before the first morphological signs of testis differentiation, which is similar to the expression profile in reptiles with TSD.
It was also shown that hypoxia disrupts primordial germ cell migration during embryonic development through the induction of insulin-like growth factor binding proteins in zebrafish temperature-dependent sex determination in vertebrates which substance in of Abilene [ 1516 ] and in the Atlantic croaker Micropogonias undulates after exposure to natural or laboratory hypoxia [ 17 ].

ZGS was responsible for drafting and revising the manuscript. Correspondence to Han-Ping Wang. This contrasts with the accepted existence of three response patterns in reptiles although perhaps they should be revisited, as done in this study with fish.
Evol Dev. Zhi-Gang Shen: moc. The expression of amh and amhr2 is associated with the development of gonadal tissue and sex change in the protandrous Black Porgy, Acanthopagrus schlegeli. High temperature causes masculinization of genetically female medaka by elevation of cortisol.
