Radiomorphometric analysis of frontal sinus for sex determination.

Journal of forensic dental sciences, 2014
Sex determination of unknown individuals carries crucial significance in forensic research, in cases where fragments of skull persist with no likelihood of identification based on dental arch. In these instances sex determination becomes important to rule out certain number of possibilities instantly and helps in establishing a biological profile of ...

The genetics of sexual development in East African cichlid fishes [PDF]

, 2015
Sexual development leads to the formation of males and females. This process can be controlled genetically, environmentally or by a combination thereof. Genetic sex determination is based on single- or polygenic actions, either linked to sex chromosomes ...

The Ovarian Transcriptome at the Early Stage of Testis Removal-Induced Male-To-Female Sex Change in the Protandrous Black Porgy Acanthopagrus schlegelii

Frontiers in Genetics, 2022
Unlike gonochoristic fishes, sex is fixed after gonadal differentiation (primary sex determination), and sex can be altered in adults (secondary sex determination) of hermaphroditic fish species. The secondary sex determination of hermaphroditic fish has

Evolutionary strata on the X chromosomes of the dioecious plant Silene latifolia: Evidence from new sex-linked genes [PDF]

, 2007
Despite its recent evolutionary origin, the sex chromosome system of the plant Silene latifolia shows signs of progressive suppression of recombination having created evolutionary strata of different X-Y divergence on sex chromosomes. However, even after

Determination of gender and stature from crown dimensions of primary teeth: An Odontometric study

Journal of Indian Society of Pedodontics and Preventive Dentistry
Background: Crown dimensions of teeth have been positively correlated with stature and gender. These odontometric values can aid significantly in the forensic identification of individuals in case of mass disasters as teeth are the least affected ...
