Inferred correlations between estimated average recombination rates and recombination distances (in brackets) with heterozygosities, nucleotide diversities, GC content, Tajima's D statistic and the numbers of non-synonymous and synonymous polymorphisms, in the two populations as measured using Spearman's ρ and Kendall's τ statistics.

Correlations which differ significantly from 0 (at the 5 per cent levels) are highlighted in bold.
