Fig 2.
Dendrogram of genetic relatedness of 11 populations from Fujian province and Taiwan.
Different populations were colored and distributed into 3 main clusters, 7 sub-clusters. Frequency values above 50 were displayed.
Fig 3.
A Hierarchical organization of the genetic structure of 11 populations from Fujian province and the Taiwan area. Each letter represents one population as marked at the right part of the map. Different colors means different groups and the number of groups (K) was set to 7 based on the method of Evanno. The length of the colored segment suggested the estimated membership proportion of each sample in the designed group. B A similar organization of the genetic structure histogram difference lies in K = 3.

MANTEL test plots of the genetic distance and geographical distance.
The vertical axis represents the genetic distance, and the abscissa axis represents the geographical distance. Both axes were standardized.
