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

Differing associations between sex determination and sex‐linked inversions in two ecotypes of Littorina saxatilis [PDF]
Evolution Letters, 2022 Sexual antagonism is a common hypothesis for driving the evolution of sex chromosomes, whereby recombination suppression is favored between sexually antagonistic loci and the sex‐determining locus to maintain beneficial combinations of alleles.

The Y chromosome sequence of the channel catfish suggests novel sex determination mechanisms in teleost fish [PDF]
BMC Biology, 2019 Background Sex determination mechanisms in teleost fish broadly differ from mammals and birds, with sex chromosomes that are far less differentiated and recombination often occurring along the length of the X and Y chromosomes, posing major challenges ...

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.

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 ...

Prediction of sex-determination mechanisms in avian primordial germ cells using RNA-seq analysis
Scientific Reports, 2022 In birds, sex is determined through cell-autonomous mechanisms and various factors, such as the dosage of DMRT1. While the sex-determination mechanism in gonads is well known, the mechanism in germ cells remains unclear.

The evolutionary process of mammalian sex determination genes focusing on marsupial SRYs [PDF]
BMC Evolutionary Biology, 2018 Maleness in mammals is genetically determined by the Y chromosome. On the Y chromosome SRY is known as the mammalian male-determining gene. Both placental mammals (Eutheria) and marsupial mammals (Metatheria) have SRY genes. However, only eutherian SRY genes have been empirically examined by functional analyses, and the involvement of marsupial SRY in ...

Evidence for avian cell autonomous sex identity (CASI) and implications for the sex-determination process? [PDF]
Chromosome Research, 2011 For the majority of animals, males and females are obviously different in terms of appearance, behaviour and physiology, and until recently, these differences were considered to be the result of hormone actions. However, there is now considerable evidence that the development of some sexually dimorphic structures/behaviours is a function of properties ...

Caste-biased Expression of fem and Amdsx Genes in Apis mellifera ligustica (Hymenoptera: Apidae)
Sociobiology, 2021 Sex determination and caste differentiation are two crucial processes for morphology building in honeybees. It is unclear whether there is an interaction between these two processes.
