RESTRICTION-ENDONUCLEASE ANALYSIS OF MITOCHONDRIAL-DNA OF MUNTJACS AND RELATED DEER

Twelve restriction endonucleases were employed to analyze the mitochondrial DNA of four species of muntjacs and two related species of deer: red muntjac (M. muntjak), Gongshan muntjac (M. gongshanensis), black muntjac (M. crinifrons), Chinese muntjac (M. reevesi), tufted deer (Elaphodus cephalophus), and forest musk deer (Moschus berezovskii). A total of 170 restriction fragments were detected among the samples. Fragments data were used to calculate the genetic distance (i.e. percent sequence divergency) among species, which in turn were used to construct a phylogenetic tree and to estimate divergency times. Our analysis indicates that the black muntjac and the Gongshan muntjac are most closely related, and that they are closely realted to the red muntjac and the Chinese muntjac. Additionally, the tufted deer is genetically closer to muntjacs than the musk deer is.
