Haplotype networks of cam (A), gapCp1 (B) and gapCp2 (C) genes for A. speciosum and A. aureum . Color circles represent haplotypes of A. aureum, and black, white and grey squares represent haplotypes of A. speciosum. a and s in the haplotype names mean A. aureum and A. speciosum, respectively. Small black circles represent hypothetical or unsampled haplotypes. Mutational steps are shown by the length of the connecting lines.
