The database is similar to the FBI's human CODIS, a computerized archive that stores DNA profiles from criminal offenders and crime scenes and is used in criminal and missing person investigations. DNA analysis and matching through the database will help law enforcement agencies to identify relationships between dogs, enabling investigators to establish connections between breeders, trainers, and dog-fight operators. Blood collected from dog fighting sites will also be searched against the Canine CODIS database to identify the source.For more background on last year's dogfighting busts in Missouri and Illinois, read "Feds Round Up Owner of Cannibal Kennel and Four Other Dog Breeders for Running an Alleged Dog-Fighting Operation."
"The Veterinary Genetics Laboratory has one of the largest sample databases in the world, said Beth Wictum, Director of the Forensics Unit of the Veterinary Genetics Laboratory in UC Davis School of Veterinary Medicine. "This is important for estimating the rarity of a DNA profile. The Canine CODIS database is unique because it includes many more DNA markers than are normally tested, and that provides greater power when calculating match probability or assigning parentage."
