Haplotype network of Y-STRs of Haplogroup O1a* individuals. As the original network was too complicated to display, here we presented the shortest tree of the largest possibility reduced from the network (this function is available in the recent versions of NETWORK program). Each node represents an O1a* STR haplotype. The lengths of the lines are proportional to the mutation steps. The broken line stands for only one step. The sizes of the nodes are proportional to their frequencies. Almost none of the ISEA haplotypes is directly linked to Taiwan aborigines, and both ISEA and Taiwanese are linked directly or indirectly to the Daic haplotypes holding the centre of the network (big green node).
