Y-Short Tandem Repeat (STR) Analysis

Forensic crime scene samples routinely contain a mixture of male and female DNA. Y-Short Tandem Repeat (Y-STR) analysis is useful to resolve mixed male and female samples since only the male DNA present in the mixture is targeted. Sexual assault cases often contain high levels of female DNA that can mask the minor male DNA present. Distinguishing the male contributor(s) in mixed sexual assault cases can lead to conclusions regarding the inclusion or exclusion of potential suspects.
