  • a P-values of the observed summary under the standard neutral model with recombination are given in parentheses. ρ/θ in simulations were sampled according to their posterior probability estimated for the Zimbabwe population (see Fig. 1C).

  • b Significant with no recombination.

  • c Significantly more variance in the summary than expected (P < 0.05).

  • d The probability of observing the one invariant locus (out of 10) in the Netherlands population is P = 0.038.
