Correlation coefficients among the studied variables: the level of neutral polymorphism (<i>θ_neu</i>), the level of normalized neutral polymorphism (<i>P_neu</i> = <i>θ_neu</i>/<i>d_neu</i>), recombination rate (RR), GC content (GC), the density of simple re

**P<1e-20. *1e-20≤P<1e-3. NSP> = 1e-3. Spearman's ρ and Kendall's τ are given at the upper and lower diagonal parts of the table, respectively. P-values are given in parentheses for marginally significant (1e-20≤P<1e-3) and nonsignificant (NS, P> = 1e-3) values.
