The minimum spanning network representing the most parsimonious mutation pathway between 6 ocelot haplotypes observed in Texas and northeastern Mexico.

Each hatch mark represents a single nucleotide point mutation. The populations in which haplotypes were observed are noted; CA = Cameron, WI = Willacy, LE = Los Ebanos, Mexico, TX = historical Texas samples. Haplotypes represented with shaded circles were observed only in museum samples originating in Texas prior to 1956.
