WebSep 1, 2007 · We present a simple model of pseudo-speciation driven only by selective mating. Using Monte Carlo simulation on a lattice we show that even without considering the genetic structure of the individuals a population living in a homogeneous habitat will divide into two, spatially separated, groups having different values of their trait. After … Population structure (also called genetic structure and population stratification) is the presence of a systematic difference in allele frequencies between subpopulations. In a randomly mating (or panmictic) population, allele frequencies are expected to be roughly similar between groups.
