  1. Shown are the rank and (detection power %) of the simulated haplotypes.
  2. aTotal extended haplotypes found are an average of all the extended haplotypes shared reaching significance from 100 simulations, which usually (depending on power) includes one simulated founder haplotype shared by two, five, or 10 samples in each simulation. The total sample size in each simulation is 1,000 and haplotypes shared by 20 samples (2%) or fewer were analyzed. When 1 cM was used as the threshold for selecting haplotypes shared pair-wise, there were five haplotypes reaching significance on average, including the simulated founder haplotype. When 0.5 cM was used as the threshold, there were 32 haplotypes reaching significance. Any of the haplotypes found repeatedly in different simulations were only counted once.
