Sex determination in mammalian germ cells
Asian Journal of Andrology, 2015 Germ cells are the precursors of the sperm and oocytes and hence are critical for survival of the species. In mammals, they are specified during fetal life, migrate to the developing gonads and then undergo a critical period during which they are ...

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

Beyond sex allocation : the role of mating systems in sexual selection in parasitoid wasps [PDF]
, 2014 Funding: UK NERC Doctoral Training GrantDespite the diverse array of mating systems and life histories which characterise the parasitic Hymenoptera, sexual selection and sexual conflict in this taxon have been somewhat overlooked.

Sex determination by osteometric assessment of the mastoid process using Cone Beam Computed Tomography [PDF]
Brazilian Dental Science, 2020 Objective: Sex determination is one of the most important parameters to identify in forensic science. Because the mastoid process is the most resistant to damage due to its position in the skull base, it can be used for sex determination. The purpose of this study was to measure the dimensions and convexity and internal angles of the mastoid process to

Sex Determination Using Mastoid Process Measurements in Brazilian Skulls [PDF]
International Journal of Morphology, 2008 Las caracteristicas del proceso mastoides son de gran utilidad para el diagnostico del sexo. De Paiva & Segre (2003) describieron que era posible el diagnostico del sexo, en base a la determinacion del area del triangulo formado entre los puntos porion, mastoidale y asterion.

Cortisol-induced masculinization: does thermal stress affect gonadal fate in pejerrey, a teleost fish with temperature-dependent sex determination? [PDF]
PLoS ONE, 2009 BACKGROUND: Gonadal fate in many reptiles, fish, and amphibians is modulated by the temperature experienced during a critical period early in life (temperature-dependent sex determination; TSD).

Sex determination using mastoid process
Asian Journal of Medical Sciences, 2015 Objective: Osteometric studies using individual bones have been a topic of interest among researchers. Such researches are a tool for conducting studies related to evolution, demographic profiles and forensic sciences. Skull is important in this regard as it resists adverse environmental conditions over time.
