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 …

Early environments can profoundly influence an organism in ways that persist over its life. In
reptiles, early thermal environments (nest temperatures) can impact offspring phenotype and …

Sexual reproduction is a fundamental aspect of life. It is defined by the occurrence of meiosis
and the fusion of two gametes of different sexes or mating types. Sex-determination …

Sex determination in animals is amazingly plastic. Vertebrates display contrasting strategies
ranging from complete genetic control of sex (genotypic sex determination) to …

Environmental DNA (eDNA) extracted from water samples has recently shown potential as a
valuable source of population genetic information for aquatic macroorganisms. This …

Sex chromosomes have evolved many times in animals and studying these replicate
evolutionary “experiments” can help broaden our understanding of the general forces …

Until recently, the field of sex chromosome evolution has been dominated by the canonical
unidirectional scenario, first developed by Muller in 1918. This model postulates that sex …

Far from the line drawings and black-and-white photos of the past, Infectious Diseases and
Pathology of Reptiles features high-quality, color photos of normal anatomy and histology …

Environmental factors affect the sex ratio of many gonochoristic fish species. They can either
determine sex or influence sex differentiation. Temperature is the most common …

Fish sex reversal is a means to understand sex determination and differentiation, but it is
also used to control sex in aquaculture. This review discusses sex reversal in gonochoristic …
