Table 2. Characteristics of autosomes and X chromosome (LG12).

Estimates are from 50 kb windows across each linkage group. Measurements are dN (rate of nonsynonymous substitutions per nonsynonymous site), dS (rate of synonymous substitutions per synonymous site) and the ratio of dN/dS (mean estimates are approximated by ΣdN/ΣdS), π (nucleotide diversity within populations). Coverage was estimated using pooled resequencing data and is shown as average coverage per base. Statistical testing was carried out using non-parametrical Mann-Whitney U test (n.s., not significant, ***, p < 0.001).
