In mammals, sex differentiation depends on gonad development, which is controlled by two groups of sex-determining genes that promote one gonadal sex and antagonize the opposite one. SOX9 plays a key role during testis development in all studied vertebrates, whereas it is kept inactive in the XX gonad at the critical time of sex determination, otherwise, ovary-to-testis gonadal sex reversal occ...

Background: Sex determination using dental features is primarily based upon the comparison of tooth dimensions in males and females. Aims and Objectives: To determine the role of inter-canine width in identification of sex of individuals. Methods: 50 subjects were included in the study. Impressions were taken with alginate and study models prepared. Inter canine width was measured in all the ca...

Sex determination is important in archeology and anthropology for the study of past societies, cultures, and human activities. Sex determination is also one of the most important components of individual identification in criminal investigations. We developed a new method of sex determination by detecting a single-nucleotide polymorphism in the amelogenin gene using amplified product-length pol...

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...

The study of teeth reveals a lot concerning forensic medicine. Particularly it is useful in human identification. In addition to determination of age, sex can also be determined from teeth. The genetic difference between males and females is defined by the presence or absence of the Y-chromosome. The majority of the DNA of the sex chromosomes is specific to either the X or Y form. There are reg...

Forensic odontology has been a vital part in investigation and presenting any dental evidence in criminal cases, mass disasters etc. Currently it has been recognized as an important tool in sex determination as well. The current article describes various methods such as visual or clinical methods, microscopic methods and advanced methods which help in sex determination. Further, it highlights i...

background detection of fetal dna in maternal blood has been examined by many research groups for a few years; thereby, scientists have a shorter way to take to approach prenatal diagnosis of abnormal pregnancies. the y chromosome sequences have recently become the most common applicable indices for fetal sex determination. objectives we conducted an algorithmic x and y mini-short tandem repeat...

In many bird species, the sex determination is very difficult in young birds and many adults. Nowadays, sex identification of animals throughout their lives is possible by molecular genetic techniques. In the present study, the sex identification of canaries by PCR methods based on chromo helicase DNA binding protein CHD-Z and CHD-W genes were explained. Genomic DNA was extracted from feather b...
