In many bird species, males and females cannot be discriminated on the basis of external characteristics. The problems associated with reliable sex identification were overcome by introducing the molecular techniques in the 1990s. These techniques are generally based on DNA hybridization or polymerase chain reaction (PCR). This paper reviews the sexing techniques, highlighting their advantages ...

Human gender identification, based on the amelogenin gene, has important applications in forensic casework, prenatal diagnosis, DNA databasing, and blood sample storage. However, we report on the first known case, in the Israeli population, of an amelogenin sex test failure on a phenotypically normal male. He was typed as a female by both the AmpF STR R © SGM plusTM and GenePrintTM kits. Subseq...

In European countries, hunting of wildlife is regulated by various directives. However, illegal activities are becoming more common. To deal with crime cases, it becomes necessary to select the best molecular markers for analysis animal sex, species, and relationships identification. This study investigated potential within chromosomal mitochondrial DNA (mtDNA) forensics. By applying targeting ...

Adolescent sex offenders increasingly are involved in the mental health delivery system. Because researchers have concluded that between 34 and 60 percent of all sexual offenses are perpetrated by adolescents, it is imperative that mental health counselors possess the knowledge and skills to appropriately identify and treat these adolescents. The authors provide information on current assessmen...

It is well known that the skull provides elements for sex identification. Twenty-two bones form the cephalic cranium and they are divided into neurocranium and splancnocranium. This research aimed to study different characteristics between skulls from both sexes by evaluating the following measurements: mastoid notch to incisive foramen (right and left side); mastoid notch to mastoid notch; and...

Early sex identification of Date Palm (Phoenix dactylifera L.) at seedling stage is an economically desirable objective, which will significantly increase the profits of seed based cultivation. The utilization of molecular markers at this stage for early and rapid identification of sex is important due to the lack of morphological markers. In this study, a total of two hundred Inter Simple Sequ...

Cognitive and olfactory deficits occur in schizophrenia, but little is known whether sex modifies these deficits. We examined the relationship between olfaction and cognition in 55 schizophrenia patients and 32 healthy controls. Patients and controls demonstrated significant differences performing cognitive tasks. In patients, sex modified all relationships of odor identification to cognition. ...

Accurate sex identification of pure line chickens in their early age has significant economic impact in breeding industry. In the recent years, range of Polymerase Chain Reaction (PCR) based sex determination techniques are routinely used to identify the sex of parent lines in breeding industries, however purified DNA is a prerequisite. Hence this study was aimed to develop a rapid and inexpens...
