Title forqs
Short Description Forward-in-time simulation of Recombination, Quantitative Traits, and Selection
Long Description forqs is a forward-in-time population genetics simulation that tracks individual haplotype chunks as they recombine each generation. forqs also also models quantitative traits and selection on those traits. forqs is implemented as a command-line C++ program, using a modular design that gives the user great flexibility in creating custom simulations. It is freely available with a permissive BSD license.
