  • Mean × 100 (95% C.I.) [number of loci; total length in base pairs] is shown. Mean is weighted by length of each locus; confidence intervals are estimated from 10,000 bootstrap replicates. NA, not applicable.

  • a Divergence at synonymous sites corrected for codon usage bias.

  • b One transposable-element region has a single highly diverged allele in the European population that may have arisen by gene conversion from another locus and was excluded from the analyses.

  • c Results are similar for the Far East vs. S. cariocanus comparisons.
