• a The median value (of 1000 iterations) of ρ as estimated by the method of Li and Stephens (2003) × 10−4; the 90% C.I. reports the 5th and 95th percentiles of the sampled values of ρ.

• b ρ as estimated by the method of Hudson (2001) × 10−4.

• c The ratio of gene conversion to recombination as estimated by the method of Hudson (2001), assuming a tract length of 300 bp.

• d Intervals (within or between subregions) for which the rate of recombination is higher than the background rate for this region; λ is the ratio of ρ for this interval to ρ for the region as a whole (see text).

• e See text for a discussion of these results for region 2.
