Fig. 1 in Populations analysis of the Brazilian Sharpnose Shark Rhizoprionodon lalandii (Chondrichthyes: Carcharhinidae) on the São Paulo coast, Southern Brazil: inferences from mt DNA sequences

Fig. 1. Median-joining haplotype network. The haplotypes are represented by circles, with the width proportional to their frequencies. Black circles correspond to Praia Grande, white to Ubatuba, and gray to Itanhaém samples. Each branch corresponds to a single mutation, except line a (with 2 mutations) and line b (with 3 mutations).
