Overview of Avian Sex Reversal [PDF]

open access: yesInternational Journal of Molecular Sciences, 2023
Sex determination and differentiation are processes by which a bipotential gonad adopts either a testicular or ovarian cell fate, and secondary sexual characteristics adopt either male or female developmental patterns. In birds, although genetic factors control the sex determination program, sex differentiation is sensitive to hormones, which can ...

Sex Reversal and Performance in Fitness-Related Traits During Early Life in Agile Frogs

open access: yesFrontiers in Ecology and Evolution, 2021
Sex reversal is a mismatch between genetic sex (sex chromosomes) and phenotypic sex (reproductive organs and secondary sexual traits). It can be induced in various ectothermic vertebrates by environmental perturbations, such as extreme temperatures or ...

Sex reversal [PDF]

open access: yesCurrent Biology, 2018
Weber and Capel discuss various aspects of sex reversal, including how it happens, why it happens in some species but not others, and whether it is adaptive.

Molecular evidence for sex reversal in wild populations of green frogs (Rana clamitans) [PDF]

open access: yesPeerJ, 2019
In vertebrates, sex determination occurs along a continuum from strictly genotypic (GSD), where sex is entirely guided by genes, to strictly environmental (ESD), where rearing conditions, like temperature, determine phenotypic sex.

Effects of natural nest temperatures on sex reversal and sex ratios in an Australian alpine skink

open access: yesScientific Reports, 2021
Altered climate regimes have the capacity to affect the physiology, development, ecology and behaviour of organisms dramatically, with consequential changes in individual fitness and so the ability of populations to persist under climatic change.

Developmental dynamics of sex reprogramming by high incubation temperatures in a dragon lizard

open access: yesBMC Genomics, 2022
Background In some vertebrate species, gene-environment interactions can determine sex, driving bipotential gonads to differentiate into either ovaries or testes. In the central bearded dragon (Pogona vitticeps), the genetic influence of sex chromosomes (

Starvation causes female-to-male sex reversal through lipid metabolism in the teleost fish, medaka (Olyzias latipes)

open access: yesBiology Open, 2020
The teleost fish, medaka (Oryzias latipes), employs the XX/XY genetic sex determination system. We show here that the phenotypic sex of medaka is affected by changes in lipid metabolism. Medaka larvae subjected to 5 days of starvation underwent female-to-

Sex-Biased Mortality and Sex Reversal Shape Wild Frog Sex Ratios

open access: yesFrontiers in Ecology and Evolution, 2021
Population sex ratio is a key demographic factor that influences population dynamics and persistence. Sex ratios can vary across ontogeny from embryogenesis to death and yet the conditions that shape changes in sex ratio across ontogeny are poorly ...

Induction of gonadal sex reversal in adult gonochorist teleost by chemical treatment: an examination of the changing paradigm

open access: yesJournal of Basic and Applied Zoology, 2020
Background Gonochorist teleosts are teleosts in which individuals develop either as males or as females, and are sexually stable thereafter throughout ontogeny.
