3.2 | Genetic differentiation and mantel test
Pairwise estimates of FST among the eastern populations
varied from 0.0015 (between LSX and NXC) to 0.2152 (between SFS and NNZ)
with an average of 0.0558, indicating low to moderate genetic
differentiation among the eastern populations. The pairwise
FST between SXX and eastern populations was generally
higher, ranging from 0.2398 (between SXX and LXW) to 0.3809 (between SXX
and SFS). The pairwise FST between SZA and eastern
populations varied from 0.1597 (between SZA and LSZ) to 0.3203 (between
SZA and SFS). There existed relatively high genetic differentiation
between SXX, SZA populations and other populations. However, the average
genetic differentiation between SYX located in middle section and
populations located in eastern section was low (FST =
0.0665) (Figure 2).
