Copyright 1994 by Robert A. Desharnais, California State University, LA NaturalSelection was created for an introductory college course in population genetics. It simulates changes in allele frequencies due to differences in viability among genotypes. Simulations can be conducted for one or two genes. For the one gene model, students can switch among several different views: allele frequency, change in allele frequency, mean fitness, or additive genetic variance. The population is represented as a black circle which moves along the graph as it evolves. In the two-gene model, the axes represent the allele frequencies of each gene. Clicking the mouse anywhere in the graph defines a set of initial conditions. The resulting trajectory shows the evolution of the population. Up to fifty simulations can be executed simultaneously. Students can set arbitary fitness values or choose from the additive, multiplicative, coadapted allele, or symmetric viability models for two genes.
