FIGURE 4. The TCS haplotype networks (mt CR) for Cottus sp. "dorofeevi" and closely related sculpins C. koshewnikowi, C. gobio, C. cyclophthalmus, and C. sibiricus: (a) completely connected haplotype network generated with the PopART 1.7 software; (b) subnetworks obtained from statistical parsimony analysis in TCS 1.21. The circle (oval, rectangle) size corresponds to haplotype frequency; dashes on the lines indicate the number of nucleotide substitutions; small circles denote extinct or unsampled haplotypes.
