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.

A multi-modal study into students’ timing and learning regulation: time is ticking [PDF]

, 2018
Purpose This empirical study aims to demonstrate how the combination of trace data derived from technology-enhanced learning environments and self-response survey data can contribute to the investigation of self-regulated learning processes. Design/

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

The evolutionary process of mammalian sex determination genes focusing on marsupial SRYs [PDF]

BMC Evolutionary Biology, 2018
Maleness in mammals is genetically determined by the Y chromosome. On the Y chromosome SRY is known as the mammalian male-determining gene. Both placental mammals (Eutheria) and marsupial mammals (Metatheria) have SRY genes. However, only eutherian SRY genes have been empirically examined by functional analyses, and the involvement of marsupial SRY in ...

Sex Determination of Dry Human Mandible Using Metrical Parameters in Mahakaushal Region of Madhya Pradesh, India: A Cross-sectional Study [PDF]

International Journal of Anatomy Radiology and Surgery, 2021
Introduction: Determination of sex and age from skeletal remains is not only important for forensic science but also for Anatomy, Forensic Odontology, Anthropology and Palaeontology examination. Mandible next to the pelvis in human remains help us in

Evidence for avian cell autonomous sex identity (CASI) and implications for the sex-determination process? [PDF]

Chromosome Research, 2011
For the majority of animals, males and females are obviously different in terms of appearance, behaviour and physiology, and until recently, these differences were considered to be the result of hormone actions. However, there is now considerable evidence that the development of some sexually dimorphic structures/behaviours is a function of properties ...

Caste-biased Expression of fem and Amdsx Genes in Apis mellifera ligustica (Hymenoptera: Apidae)

Sociobiology, 2021
Sex determination and caste differentiation are two crucial processes for morphology building in honeybees. It is unclear whether there is an interaction between these two processes.

Transcriptome sequencing and screening of genes related to sex determination of Trichosanthes kirilowii Maxim

PLoS ONE, 2020
Trichosanthes kirilowii Maxim. (TK) is a dioecious plant in the Cucurbitaceae for which different sexes have separate medicinal uses. In order to study the genes related to sex determination, transcriptome sequencing was performed on flower buds of male ...

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 ...

Sex determination in honeybees: two separate mechanisms induce and maintain the female pathway. [PDF]

PLoS Biology, 2009
Organisms have evolved a bewildering diversity of mechanisms to generate the two sexes. The honeybee (Apis mellifera) employs an interesting system in which sex is determined by heterozygosity at a single locus (the Sex Determination Locus) harbouring ...
