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.

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 ...

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 ...

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 ...

Expectation-Maximization Algorithm for Determining Natural Selection of Y-Linked Genes Through Two-Sex Branching Processes [PDF]

Journal of Computational Biology, 2012
A two-dimensional bisexual branching process has recently been presented for the analysis of the generation-to-generation evolution of the number of carriers of a Y-linked gene. In this model, preference of females for males with a specific genetic characteristic is assumed to be determined by an allele of the gene.

Annual variation in the levels of transcripts of sex-specific genes in the mantle of the common mussel, Mytilus edulis [PDF]

, 2012
Mytilus species are used as sentinels for the assessment of environmental health but sex or stage in the reproduction cycle is rarely considered even though both parameters are likely to influence responses to pollution.

Simulation as a method for asymptotic system behavior identification (e.g. water frog hemiclonal population systems) [PDF]

, 2020
Studying any system requires development of ways to describe the variety of its conditions. Such development includes three steps. The first one is to identify groups of similar systems (associative typology).
