Comparative RNA-Seq Analysis of Differentially Expressed Genes in the Testis and Ovary of Mudskipper, <i>Boleophthalmus pectinirostris</i>. [PDF]

Animals (Basel)
Sex determination and differentiation in teleosts are governed by complex genetic regulatory networks that include evolutionarily conserved mechanisms. In this study, we investigated Boleophthalmus pectinirostris, a Gobiidae species lacking heterogametic

Sex determination mode does not affect body or genital development of the central bearded dragon (Pogona vitticeps)

EvoDevo, 2017
Background The development of male- or female-specific phenotypes in squamates is typically controlled by either temperature-dependent sex determination (TSD) or chromosome-based genetic sex determination (GSD).

The Staurotypus turtles and aves share the same origin of sex chromosomes but evolved different types of heterogametic sex determination.

PLoS ONE, 2014
Reptiles have a wide diversity of sex-determining mechanisms and types of sex chromosomes. Turtles exhibit temperature-dependent sex determination and genotypic sex determination, with male heterogametic (XX/XY) and female heterogametic (ZZ/ZW) sex ...

Sex Determination and Differentiation in Teleost: Roles of Genetics, Environment, and Brain

Biology, 2021
The fish reproductive system is a complex biological system. Nonetheless, reproductive organ development is conserved, which starts with sex determination and then sex differentiation.

Sex determination without sex chromosomes

Philosophical Transactions of the Royal Society of London. Biological Sciences, 2021
With or without sex chromosomes, sex determination is a synthesis of many molecular events that drives a community of cells towards a coordinated tissue fate.

femaleless Controls Sex Determination and Dosage Compensation Pathways in Females of Anopheles Mosquitoes

Current Biology, 2021
Summary The insect sex determination and the intimately linked dosage compensation pathways represent a challenging evolutionary puzzle that has been solved only in Drosophila melanogaster.

Unusual Mammalian Sex Determination Systems: A Cabinet of Curiosities

Genes, 2021
Therian mammals have among the oldest and most conserved sex-determining systems known to date. Any deviation from the standard XX/XY mammalian sex chromosome constitution usually leads to sterility or poor fertility, due to the high differentiation and ...

Sex-limited chromosomes and non-reproductive traits

BMC Biology, 2022
Sex chromosomes are typically viewed as having originated from a pair of autosomes, and differentiated as the sex-limited chromosome (e.g. Y) has degenerated by losing most genes through cessation of recombination.

Evolutionary and demographic consequences of temperature-induced masculinization under climate warming: the effects of mate choice

BMC Ecology and Evolution, 2021
Background One of the dangers of global climate change to wildlife is distorting sex ratios by temperature-induced sex reversals in populations where sex determination is not exclusively genetic, potentially leading to population collapse and/or sex ...

Sex Determination Using Mastoid Process Measurements in Brazilian Skulls [PDF]

International Journal of Morphology, 2008
Las caracteristicas del proceso mastoides son de gran utilidad para el diagnostico del sexo. De Paiva & Segre (2003) describieron que era posible el diagnostico del sexo, en base a la determinacion del area del triangulo formado entre los puntos porion, mastoidale y asterion.
