Capabilities and Services
The primary function of the Forensic Biology discipline is the identification of biological material and the use of DNA analysis to determine whether the biological material could have originated from a specific individual.
The Forensic Biology discipline provides three types of service: biological screening of forensic casework, DNA analysis of forensic casework, and DNA analysis of offender samples. Separate scientific reports are issued for biological screening and DNA testing of forensic casework.
The laboratory also issues CODIS hit letters to notify law enforcement when there is a DNA match between samples in the DNA database. CODIS hits are investigative leads, typically identifying a potential source of biological material from crime scene evidence.

Y-Chromosome DNA (Y-STR DNA)
Male specific DNA found in the nucleus of most cells of the body. Y-STR analysis is used to amplify locations on the Y chromosome and Y-STR data can only be obtained from male individuals. This type of DNA is inherited paternally. This type of testing may be useful when samples are mixtures of male and female DNA or when there is very little DNA from a male contributor. Y-STR testing has its limitations since close male relatives will have the same Y-STR profile.
