The demographic model used to simulate the CEU and YRI populations. The model is shown with time flowing downward. Model parameters are as described by Gravel et al. (2011), including a growth rate of 0.48% per generation in the European expansion period. We simulated an allele under positive selection (s = 0.02, 0.005) introduced 20, 25, and 50 kya (assuming 25 years per generation).
