Comparative transcriptome analysis reveals differentially expressed genes and signaling pathways between male and female mature gonads of Hemibarbus maculatus

open access: yesJournal of the World Aquaculture Society, 2023
Hemibarbus maculatus is a globally important species for its value in fisheries and aquaculture. There is relatively little information available about this species' sexual development genes.

Conflict over condition-dependent sex allocation can lead to mixed sex-determination systems [PDF]

open access: yes, 2014
Theory suggests that genetic conflicts drive turnovers between sex-determining mechanisms, yet these studies only apply to cases where sex allocation is independent of environment or condition.

Independent stratum formation on the avian sex chromosomes reveals inter-chromosomal gene conversion and predominance of purifying selection on the w chromosome [PDF]

open access: yes, 2014
We used a comparative approach spanning three species and 90 million years to study the evolutionary history of the avian sex chromosomes. Using whole transcriptomes, we assembled the largest cross-species dataset of W-linked coding content to date.

Oviposition but not sex allocation is associated with transcriptomic changes in females of the parasitoid wasp Nasonia vitripennis [PDF]

open access: yes, 2015
This work was supported by Natural Environment Research Council (NERC) grant (NE/J024481/1). DMS was previously funded by a NERC Advanced Research Fellowship.Linking the evolution of the phenotype to the underlying genotype is a key aim of evolutionary ...

The Biological Basis of Binary Sex Differentiation [PDF]

open access: yes, 2023
While gender is (by definition) influenced by social factors and hence subject to change as society changes, sex reflects biology, which is fixed in the time scale of a human lifepan. Gender, given its definition, may not fit into two categories.

A clinical approach to diagnosis of ambiguous genitalia

open access: yesJournal of Indian Association of Pediatric Surgeons, 2019
Disorders of sex development (DSD) are a sensitive and stressful condition for the family as well as the treating physician to deal with. The main issue in managing such cases is sex assignment.

Sex differentiation and sex reversal in Atlantic Slamon (Salmo salar) [PDF]

open access: yes, 2021
This thesis provides original and substantial understanding into: the timing of sex differentiation; the age at which sex differentiation can be manipulated by application of an exogenous androgen or type II aromatase inhibitor; and the roles of several ...

Sex chromosome differentiation. [PDF]

open access: yes, 2014
A. Reconstructed evolutionary path of sex chromosome differentiation in humans. Sex chromosomes originate from autosomes that acquired a sex-determining function (the Sry gene) after their split from monotremes.

Differential Expression of miRNAs, lncRNAs, and circRNAs between Ovaries and Testes in Common Carp (Cyprinus carpio)

open access: yesCells, 2023
Female common carp grow faster than male individuals, implying that rearing females could be more profitable in aquaculture. Non-coding RNAs (ncRNAs) serve as versatile regulators with multiple functions in diverse biological processes.

Can Individuals with 47,XYY Karyotypes Exist without Male Phenotype? A Narrative Literature Review and Case Report

open access: yesFrontiers in Bioscience-Scholar
Background: The 47,XYY syndrome is a genetic condition found in about 1 in 1000 male children. The expected phenotype is male but could vary greatly.
