Source code to simulate Fisher's geometric model for two populations in allopatry, used afterwards to study the fitness of hybrids.

This code has been used for the paper:

• A. Simon, N. Bierne and J. J. Welch. "Coadapted genomes and selection on hybrids: Fisher’s geometric model explains a variety of empirical patterns". Evolution Letters, 2018. https://doi.org/10.1002/evl3.66

The C++ source code is the work of Christelle Fraïsse and colleagues and has been slightly modified to fit our framework:

• C. Fraïsse, P. A. Gunnarsson, D. Roze, N. Bierne, and J. J. Welch. "The Genetics of Speciation: Insights from Fisher’s Geometric Model". Evolution 70, no. 7 (2016): 1450–64. https://doi.org/10.1111/evo.12968.

This source code uses the Mersenne Twister pseudo-random generator:

• M. Matsumoto and T. Nishimura, "Mersenne Twister: A 623-Dimensionally Equidistributed Uniform Pseudo-Random Number Generator", ACM Transactions on Modeling and Computer Simulation, Vol. 8, No. 1, January 1998, pp 3-30.

R scripts produce Figures S2 to S4 by using included results of the simulations.
