Sympatric Speciation in Threespine Stickleback: Why Not?
An illustration of the simulated dynamics of the phenotype distribution over time, using parameter values that lead to rapid speciation. Darker shading indicates greater numbers of individuals for a given phenotype at a given time. Parameter values are population size = 500, number of loci = 40, initial allele frequency = 0.5, , and assortative mating correlation .
