Fig. 2From: Genetic diversity and variation of seven Chinese grass shrimp (Palaemonetes sinensis) populations based on the mitochondrial COI geneTCS network of P. sinensis based on COI haplotypes. The sizes of the circles indicate the number of individuals with each given haplotype. The number in the bracket represents the mutation steps between haplotypes and the black circles on the line represent an additional mutational changeBack to article page
