Background: Sex determination in vertebrate embryos has long been equated with gonadal
differentiation into testes or ovaries. This view has been challenged over the years by …

Charles Darwin first provided a lucid explanation of how gender differences evolve nearly
140 years ago. Yet, a disconnect remains between his theory of sexual selection and the …

Bisphenol A (BPA) is an abundant endocrine-disrupting compound that is found in the
aquatic environment and has adverse effects on fish reproduction; however, the exact …

Many basic cellular processes are shared across vast phylogenetic distances, whereas sex-
determining mechanisms are highly variable between phyla although the existence of two …

Since the first volume of The Biology of Sea Turtles (Lutz and Musick, 1997), studies using
molecular techniques to address a variety of questions about sea turtle biology and life …

Background The mechanism of sex determination in zebrafish is largely unknown and
neither sex chromosomes nor a sex-determining gene have been identified. This indicates …

Sex determination in vertebrates, the process of forming an ovary or testis from a bipotential
gonad, can be initiated by genetic or environmental factors. Elements of the downstream …

Since the first volume of The Biology of Sea Turtles was published in 1997, the field has
grown and matured in ways few of the authors would have predicted—particularly in the …

Although gonadogenesis has been extensively studied in vertebrates with genetic sex
determination, investigations at the molecular level in nontraditional model organisms with …

The developmental processes underlying gonadal differentiation are conserved across
vertebrates, but the triggers initiating these trajectories are extremely variable. The red …
