Dendrogram constructed using noncoding sequences of neo-Y and neo-X fragments. A total of 35.1-kilobase noncoding sequences of neo-Y and neo-X alleles in the black muntjac and the orthologous sequences in the Indian muntjac as the outgroup were used to construct the dentrogram. 'BM' stands for 'male black muntjac'; 'IM' stands for 'Indian muntjac'; '1'and '2' represent the two male black muntjac individuals separately. (a) Tree constructed by neighbor-joining method. Branch lengths calculated using Kimura's two-parameter method are shown above the corresponding branches. (b) Tree constructed by maximum likelihood method. Branch lengths calculated by baseml in PAML package using 'HKY85' method were shown above the corresponding branches.
