Background: Determining gender is one of the most important parameters in forensic identification. Teeth are an excellent material in living and nonliving populations for anthropological, genetic, odontologic and forensic investigations being hardest and chemically the most stable tissue in the body, selectively preserved and fossilized, thereby providing the best records for evolutionary chang...

OBJECTIVE To assess the accuracy of fetal sex determination at 11-14 weeks of gestation. METHODS Fetal gender assessment by ultrasound was prospectively carried out in 172 singleton pregnancies at 11-14 weeks of gestation immediately before chorionic villus sampling for karyotyping. The genital region was examined in a midsagittal plane and the fetal gender was assigned as male if the angle o...

The pearl industry in French Polynesia is based on exploitation of natural stocks of the blacklip pearl oyster (Pinctada margaritifera). It generates an annual turnover of €90 million. Improvements in pearl quality need genetic studies to improve the populations. This pearl oyster is a protandric species, in which the sex ratio normally is biased toward males. There is an increasing interest in...

Establishing the gender of a dead person is an important procedure in forensic medicine, especially during mass disasters. Teeth are very important material as they are available even after considerable postmortal changes because they are resistant to chemical and mechanical agents. The results of this study indicate that there are significant differences between the sexes in canine dimorphism....

Background: Fast and secure identification processes in forensic odontology can be a very difficult process. Probably the most common techniques used are Dental, fingerprint and DNA comparisons. Since these techniques cannot always be used, it is necessary to apply different and less known techniques such as cheiloscopy. Due to its special features, lip groove can be used successfully in human ...

Determination of gender from human DNA samples is a common problem in forensic laboratories. While several PCR-based assays are currently available for human sex typing, each of the current approaches has limitations. Methods based on male-specific amplification, such as the amplification of the SRY locus [1], lack an internal positive control to discriminate between female DNA and male DNA whi...

Gender identification of sexually monomorphic mammals can be difficult. We used analysis of zinc-finger protein (Zfx and Zfy) DNA regions to determine gender of 96 beavers (Castor canadensis) from 3 areas and used these results to verify gender determined in the field. Gender was correctly determined for 86 (89.6%) beavers. Incorrect assignments were not attributed to errors in any one age or s...
