Fig. 3. Dendrogram generated by unweighted pair group method with arithmetic means based on Dice (1945) coefficients. The clusters correspond to the populations, indicated at the right of the dendrogram. The mixed cluster includes individuals from the Negro Brillante (NB), Negro Opaco (NO), and wild (W) populations (see text for composition). Individuals listed at the right constitute exceptions to the clustering into the Beige, Negro Brillante, Negro Opaca, Rojo, and wild populations. All 170 haplotypes are shown in this figure, although some haplotypes were observed in more than one individual.
