A transgenerational endocrine signaling pathway in Crustacea. [PDF]

PLoS ONE, 2013
Environmental signals to maternal organisms can result in developmental alterations in progeny. One such example is environmental sex determination in Branchiopod crustaceans.

Sex determination: Co-opted signals determine gender [PDF]

, 2000
The Drosophila JAK–STAT pathway and its ligand Unpaired are required for a wide range of developmental processes. Recent results have identified Unpaired as an activator of sex-lethal and revealed a new role for the JAK–STAT pathway in sex ...

ATAC-seq and RNA-seq analysis unravel the mechanism of sex differentiation and infertility in sex reversal chicken

Epigenetics & Chromatin, 2023
Background Sex determination and differentiation are complex and delicate processes. In female chickens, the process of sex differentiation is sensitive and prone to be affected by the administration of aromatase inhibitors, which result in chicken sex ...

Evolution of "determinants" in sex-determination: a novel hypothesis for the origin of environmental contingencies in avian sex-bias. [PDF]

, 2009
Sex-determination is commonly categorized as either "genetic" or "environmental"-a classification that obscures the origin of this dichotomy and the evolution of sex-determining factors.

A new application of morphometric variables and image processing to determine day-old chicken sex

Journal of Applied Research and Technology, 2022
One of the principal activities in the poultry industry is determine the sex of chickens of one day old. In this paper, we present a non-invasive technique to determine the sex of day-old chickens based on image processing algorithms. The technique analyzes morphometrical attributes from chicken using the slow and rapid growth of primary and secondary ...

Sex determination using mastoid process length in dry skulls of Nigerian population

MOJ Anatomy & Physiology, 2020
Introduction: Identification of an individual is very crucial in any medicolegal investigation. Age, sex and stature are the primary factors that help in the identification. Skull is important in this regard as it resists adverse environmental conditions over time.

Discovery of Sexual Dimorphisms in Metabolic and Genetic Biomarkers [PDF]

, 2011
Metabolomic profiling and the integration of whole-genome genetic association data has proven to be a powerful tool to comprehensively explore gene regulatory networks and to investigate the effects of genetic variation at the molecular level.

Endosymbionts interacting with sex-determining genes and processes

Current Opinion in Insect Science
Insects are rich in reproductive diversity and in maternally inherited symbionts. Maternal inheritance has selected for a suite of microbial mechanisms that enhance host fitness and skew sex ratios in favor of females. Recently, there has been significant progress in characterizing the genetic and cellular mechanisms that these maternally transmitted ...
