Abstract

Background:b> In sexual-assault cases, it was found that autosomal the analysis of DNA of gynecological swabs is a challenge, because if we find a large quantity of female material it may prevent detection of the male DNA. The solution to this problem was doing differential DNA extraction. The use of Y-chromosome genetic markers, such as short tandem repeats (STRs), helps the amplification of low quantities of male DNA independently of the victim’s DNA background.

Results: In the present case a young male was found dead under the balcony of newly married wife there were a suspect of illegal relationship, the use of Y- STR used to solve this case.

Conclusion: Y-STR is very useful in solving the cases of sexual assault with a small amount of male DNA.
