GSR: Simulator - ForwSim

Basic Package Attributes
Title ForwSim
Short Description The program given below is based on the algorithm described in Padhukasahasram et al. 2008 to simulate genetic drift in a standard Wright-Fisher process.
Long Description Diploid organisms are represented as pairs of chromosome arrays that store the locations of mutations. The user specifies a probability of selfing. Populations of constant size reproduce with non-overlapping generations. Mutations occur at a Poisson-distributed rate and insert new integers into chromosome arrays, which may undergo recombination. The number of sites is finite, but mutations occur only at non-polymorphic sites. Locations which are no longer polymorphic are removed. If using natural selection, the evolution of selected and neutral sites is carried out separately, with selected sites considered first.
