Str sex

For forensic labs, the most common application of Y-STRs is in criminal cases such as sexual assault, where evidence samples are difficult to resolve with traditional autosomal STR analysis due to low amounts of male DNA present in a high background of female DNA. Y-STR analysis is also a valuable tool to trace familial relationships among males, to help identify missing persons, and to assess paternal relationships when the alleged father is not available. Jack Ballantyne from the University of Central Florida explains that Y-STR analysis can help in such cases and it is a mere extension of standard methodology that labs are using today.

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 polymorphisms in combination with sex-determining region Y analysis. We particularly focused on the most common types of postmortem DNA damage in ancient and forensic samples: fragmentation and nucleotide modification resulting from deamination.
