marginally significantp = 0.029
This hypothesis fits to our data as genetic diversity ( H e ) and the proportion of polymorphic loci (MAC ≥2) were slightly higher but significant or marginally significant in the southern group (0.803 vs. 0.798, Mann–Whitney U test, p = 0.029; 3821 vs. 3090, Mann–Whitney U test, p = 0.052).
