Comparison of mitochondrial DNA and SRY-promoter phylogenies on chamois. Neighbor-Joining trees under Jukes-Cantor showing the relationships among chamois and the outgroups Ovis aries, Capra hircus and Bos taurus. a) Tree constructed with a combined sequence of 1708 nucleotides of mtDNA . Sequences in clades mtW, Clade mtC and Clade mtE, in black, grey and white respectively, were collapsed. b) Tree constructed with a sequence of 531 nucleotides of the SRY promoter. For both trees the number of individuals in the external branches is indicated in parentheses.
