  • a Total number of chromosomes under the standard neutral Wright–Fisher model with constant population size and uniform mutation and recombination rates.

  • b Per-generation per-sequence mutation rate.

  • c Per-generation per-sequence recombination rate.

  • d Probability of selfing.

  • e FORWSIM is our forward simulation program written in C++ and is freely available at http://people.cornell.edu/pages/bp85.

  • f ms is a C program that simulates data sets under the coalescent framework and is freely available at http://home.uchicago.edu/∼rhudson1/source.html. ms was run with the population crossing-over rate ρ = 4Nr and population mutation rate θ = 4Nu.

  • g Total number of SNPs for a sample size of 20 chromosomes. Average values are based on 1000 simulations.

  • h Number of distinct haplotypes. Average values are based on a sample of 20 chromosomes and 1000 simulations.
