Figure 4.

Graph of relationships between genetic and geographic distances. a) Relationships between Leucetta chagosensis log-transformed gene flow parameters (M) and log-transformed distances (km) of the 15 population subset. Thick lines indicate the Reduced Major Axis Regression. Mantel tests revealed a significant major axis regression slope of -0.3451 (P = 0.0144). b) The same relationships for the 8 population subset. Mantel test revealed a significant major axis regression slope of -0.4177 (P = 0.0332).
