Figure 2
Median-joining network showing relationships among Lightiella magdalenina haplotypes and other cephalocarids and remipedes. Median-joining network based on COI (a) and Cyt b (b) datasets. The number of point mutations is reported along the lines connecting haplotypes. Rings on the nodes show median vectors, representing hypothetic connecting sequences, calculated with the maximum parsimony method. Pie sizes are proportional to the absolute frequency of each haplotype/sequence. Due to graphical representation issues the length of edges connecting L. magdalenina haplotypes is not exactly proportional to the number of mutating positions between haplotypes. The sample codes are reported in Figure 1. For species abbreviations, refer to the main text.
