A molecular genetic approach for species identification of mammals and sex determination of birds in a forensic case of poaching from South Korea

Abstract

DNA-based analysis was performed using partial mitochondrial cytochrome b genes of five mammalian specimens and Chromo-Helicase-DNA-binding (CHD) genes of five pheasants to determine whether specimens were from illegally hunted animals. Mammalian specimens were identified as being those of horse, roe deer, and cow through gene amplification using cytb981f and cytb981r primer set and sequencing. CHD genes were revealed to be those of three male and two female pheasants through polymerase chain reaction amplification. Because hunting of roe deers and female pheasants is prohibited in Korea, these results provided forensic evidences of illegal wild animal hunting.
