simMSG

simMSG diagram

We developed this simulator to help design MSG genotyping experiments in natural and artificial hybrids. This figure (from Schumer & Cui et al in press) shows MSG plots for different types of hybrid crosses that can be generated using simMSG.

admix'em

admixem diagram

admix'em is a flexible forward time simulator of admixture with selection. The major advantage of admix'em is its ability to implement complex selection. We recently used admix'em to test a new model for the evolution of hybrid reproductive isolation by fixation of parental incompatibilities. Shown here are the trajectories of incompatibility pairs in hybrid populations at different population sizes (from Schumer et al. 2015).
