Ground-breaking DNA study suggests that South African leopards may be unique. This is according to the study on African leopards published in the journal PeerJ by a team of international scientists led by Professor Yoshan Moodley of the Department of Biological Sciences, Faculty of Science, Engineering and Agriculture at the University of Venda and Dr Declan Morris of the University of Adelaide, Australia. The team investigated mitochondrial DNA, which is only passed on by females, and found that all African leopards belong to one of two maternal DNA lines.
