Identification of a sex-linked SNP marker in the salmon louse (Lepeophtheirus salmonis) using RAD sequencing [PDF]

, 2013
The salmon louse (Lepeophtheirus salmonis (Krøyer, 1837)) is a parasitic copepod that can, if untreated, cause considerable damage to Atlantic salmon (Salmo salar Linnaeus, 1758) and incurs significant costs to the Atlantic salmon mariculture ...

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 ...

Sex determination in Bonellia viridis (Echiura : Bonelliidae) : population dynamics and evolution [PDF]

, 2005
In the echiuran worm Bonellia viridis Rolando, the vast majority of sexually undifferentiated larvae metamorphose into dwarf males that live inside the female when exposed to females, but differentiate into females when developing in the absence of ...

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 ...

Transitions in sex determination and sex chromosomes across vertebrate species [PDF]

, 2018
Despite the prevalence of sexual reproduction across eukaryotes, there is a remarkable diversity of sex determination mechanisms. The underlying causes of this diversity remain unclear, and it is unknown if there are convergent trends in the ...

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 ...

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 ...
