Simulation of genome sequences, population structure, and genetic architecture. (A) Three populations (P1, P2, P3) were simulated with an effective population size of 20,000 each. P1 and P2 diverged 1,000 generations before present and P1 and P3 diverged 2,000 generations ago. (B) 1,000 independently inherited chromosomes were simulated, each containing one QTL. Three sets of variants were considered, including “causal”, “tag”, and “all” as illustrated. (C) Six different genetic architecture were simulated, each illustrated by one of the panels.
