Dmrt1 polymorphism covaries with sex-determination patterns in Rana temporaria. [PDF]
, 2016 Patterns of sex-chromosome differentiation and gonadal development have been shown to vary among populations of Rana temporaria along a latitudinal transect in Sweden.

Histological and transcriptomic effects of 17α-methyltestosterone on zebrafish gonad development
BMC Genomics, 2017 Background Sex hormones play important roles in teleost ovarian and testicular development. In zebrafish, ovarian differentiation appears to be dictated by an oocyte-derived signal via Cyp19a1a aromatase-mediated estrogen production.

Using conventional F-statistics to study unconventional sex-chromosome differentiation. [PDF]
, 2017 Species with undifferentiated sex chromosomes emerge as key organisms to understand the astonishing diversity of sex-determination systems. Whereas new genomic methods are widening opportunities to study these systems, the difficulty to separately ...

Long-Term Follow-Up of Patients with 46,XY Partial Gonadal Dysgenesis Reared as Males
International Journal of Endocrinology, 2014 Background/Aims. Studies on 46,XY partial gonadal dysgenesis (PGD) have focused on molecular, gonadal, genital, and hormone features; little is known about follow-up. Our aim was to analyze long-term outcomes of PGD. Methods.

UBE2I stimulates female gonadal differentiation in chicken (Gallus gallus) embryos
Journal of Integrative Agriculture, 2021 Without known analogous sex-determining factors like SRY (sex determining region Y) in mammals, the chicken (Gallus gallus) sex determination mechanism still remains unclear, which highly restricts the biological research on chicken development and ...

Host resistance does not explain variation in incidence of male-killing bacteria in Drosophila bifasciata [PDF]
, 2004 Background Selfish genetic elements that distort the sex ratio are found widely. Notwithstanding the number of records of sex ratio distorters, their incidence is poorly understood.

A genetic basis for a postmeiotic X versus Y chromosome intragenomic conflict in the mouse. [PDF]
, 2012 Intragenomic conflicts arise when a genetic element favours its own transmission to the detriment of others. Conflicts over sex chromosome transmission are expected to have influenced genome structure, gene regulation, and speciation.

The "backdoor pathway" of androgen synthesis in human male sexual development. [PDF]
, 2019 Mammalian sex determination (male versus female) is largely controlled by genes, whereas sex differentiation (development of reproductive structures) is largely controlled by hormones. Work in the 20th century indicated that female external anatomy was a

Scientific Reports, 2019 This study investigated whether irradiation of a specific light wavelength could affect the sex differentiation of fish. We first found that the photoreceptor genes responsible for receiving red, green, and ultraviolet light were expressed in the eyes of
