• Ccon θ, π are given per site. In-del variation is included in calculations of θ and π.

• a Number of alleles sampled.

• b The population recombination rate for which our haplotype test (see Table 4) P is maximal.

• c Watterson's (1975) estimate.

• d Based on 21% In(2L)t frequency. Assuming other compatible In(2L)t frequencies did not significantly change these estimates.

• e Tajima's test by simulation (see methods); P > 0.10 when C = 0; P = 0.001 when C = Clab.
