Figure 2From: Molecular evidence for natural hybridization in the mangrove fern genus AcrostichumHaplotype 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.Back to article page
