Population structure analyses results from GenAlEx suggests moderate population structuring among
the four sampled groups. FST values were high to moderate ranging from a high of 0.237 between BC and
NB to a low of 0.101 between BC and PS (Table 2). All FST values were found to be significant using FSTAT.
Population structuring is visually represented with distinct groupings in the Principal Coordinate
Analysis (PCoA) graph from GeneAlEx describing 57.11% of the genetic variation and suggesting four
distinct clusters. Even though there were four distinct groupings there was also overlap of individuals
between all groups most notably with the NB cluster overlapping all other groups although distinct in its
own segment of the graph (Figure 1).
