Data from 100 simulations for migration values of 1%, 5%, 10%, 20%, 30%, and 40%. Each curve represents a single admixed population. To generate the plots, 100 chromosomes were sampled from each population at exponentially growing time points, and the following statistics for each chromosome in each sampled generation were collected: (a) admixture rate; (b) number of breakpoints; black lines indicate the expected value, given by: Nbkpts = 2TgenR(Eα(1 - Eα) - var α); and (c) the WT centers. Inset: Average number of breakpoints for each simulation parameter. Black lines indicate the expected value.
