TL;DR: Rec recombinant breakpoint analysis is used to restrict the sex-determining region in medaka fish to a 530-kilobase stretch of the Y chromosome, and it is suggested that thesex-specific DMY is required for testicular development and is a prime candidate for the medaka sex-Determining gene.

TL;DR: It is concluded that estradiol, aromatase activity and estrogen receptor in the ovarian tissue play an important role in the natural and controlled sex change in black porgy.

TL;DR: In transient transfection assays using mammalian COS-7 cells, both tERα and tERβ showed estradiol-17β dependent activation of transcription from the estrogen-responsive ERE-Luc promoter, the first report of the presence of ERα and ERβ within a single non-mammalian vertebrate species.

TL;DR: Sequence and phylogenic analyses showed that the goby P450arom forms belong to two separate CYP19 subfamilies, and findings suggest that P 450aromA, but not P450b, is involved in regulating ovarian vitellogenesis in goby.

TL;DR: It is demonstrated terminal phase males inhibit sex change regardless of their size relative to the female, which may indicate normal ovarian function whereas ovaries of other treatment groups appear quiescent or are undergoing sex change.
