A diverse array of sex determination (SD) mechanisms, encompassing environmental to
genetic, have been found to exist among vertebrates, covering a spectrum from fixed SD …

Sex is prevalent in nature and sex determination is one of the most fundamental biological
processes, while the way of initiating female and male development exhibits remarkable …

The evolution of gene expression in mammalian organ development remains largely
uncharacterized. Here we report the transcriptomes of seven organs (cerebrum, cerebellum …

Gonadal sex determination in vertebrates generally follows a sequence of genetically
programmed events. In what is seemingly becoming a pattern, all confirmed or current …

Sexual dimorphism is one of the most pervasive and diverse features of animal morphology,
physiology, and behavior. Despite the generality of the phenomenon itself, the mechanisms …

Background Despite the popularity of zebrafish as a research model, its sex determination
(SD) mechanism is still unknown. Most cytogenetic studies failed to find dimorphic sex …

The zebrafish (D anio rerio) is a freshwater teleost of the family C yprinidae that is
established as a model organism in many research fields. Here, we define the …

Although the genetic triggers for gonadal sex differentiation vary across species, the cell
biology of gonadal development was long thought to be largely conserved. Here, we present …

Thyroid hormones (THs) are well-known regulators of development and metabolism in
vertebrates. There is increasing evidence that THs are also involved in gonadal …

Gametogenesis, the process of forming mature germ cells, is an integral part of both an
individual's and a species' health and well-being. This chapter focuses on critical male and …
