Fig. 5

The fastSTRUCTURE bar plot showing the genetic clusters. The assignment probabilities (K = 5; the number of populations or clusters that the samples are best divided into) of each genotyped individual of BMSB from 12 different geographical regions were shown. Each pixel column on x-axis is one individual sample. The proportion of genetic components belonging to different genetic clusters for each individual is represented on the y-axis. Different colours in a bar represent proportion of the genomic component in a sample derived from different populations. Dotted line was used to divide BMSB populations from different countries
