Single-step PCR-based genetic sex determination of rat tissues and cells

BioTechniques, 2017
The advent of genome editing strategies has expanded the range of animal models available for gene manipulation and renewed research interest in the rat. Gender is a key variable for in vivo gene function analyses.

The rise and fall of the ancient northern pike master sex-determining gene

eLife, 2021
The understanding of the evolution of variable sex determination mechanisms across taxa requires comparative studies among closely related species. Following the fate of a known master sex-determining gene, we traced the evolution of sex determination in

Genotype-by-environment interactive effects and conflict solving during gonadal sex differentiation of pejerrey Odontesthes bonariensis, a fish with dual genotypic/environmental sex determination

Biology of Sex Differences
Background Genotypic (GSD) and environmental (ESD) sex determination coexist in many species of reptiles, fish, and amphibians. Inherited genotypic signals and environmental factors conceivably interact as pro-testis or pro-ovary signals during sex ...

Sex Determination in Plants [PDF]

Plant Signaling & Behavior, 2007
Most dioecious plant species are believed to derive from hermaphrodite ancestors. The regulatory pathways that have been modified during evolution of the hermaphrodite ancestors and led to the emergence of dioecious species (with separate sexes) still remain unknown. Silene latifolia is a dioecious plant species harbouring XY sex chromosomes.

Identification of sex determination locus in sea cucumber Apostichopus japonicus using genome-wide association study

BMC Genomics, 2022
Background Sex determination mechanisms are complicated and diverse across taxonomic categories. Sea cucumber Apostichopus japonicus is a benthic echinoderm, which is the closest group of invertebrates to chordate, and important economic and ecologically

Mismatches between the genetic and phenotypic sex in the wild Kou population of Nile tilapia Oreochromis niloticus [PDF]

PeerJ, 2019
Sex determination and sex chromosomes can be very diverse between teleost species. The group of tilapias shows a polymorphism in sex determination not only between closely related species but also between domestic strains within a species.

Comparative RNA-Seq Analysis of Differentially Expressed Genes in the Testis and Ovary of Mudskipper, Boleophthalmus pectinirostris

Animals
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

Do pregnant women want to know the sex of the expected child at routine ultrasound and are they interested in sex selection?

Upsala Journal of Medical Sciences, 2017
Background: The aim of the study was to investigate if expecting parents wanted to know the sex of the fetus during ultrasound examination and if they had discussed it with the midwife. Another aim was to explore any interest in sex selection. Methods: A

Highlighting the Importance of Correct Sex Identification in Chondrichthyan Genomic Studies, Using the White Shark as an Example

Fishes
The increased availability of reference genome assemblies of sharks and rays has contributed greatly to our understanding of their biology, including their sex-determination mechanisms.

Identification of sex-determination regions and development of male-specific markers for topmouth culter (Culter alburnus)

Aquaculture Reports
The topmouth culter (Culter alburnus), a carnivorous freshwater species in the family Cyprinidae (order Cypriniformes), holds high economic value and displays marked sexual dimorphism in growth, where females exhibit accelerated growth relative to males.
