Abstract: We have used the Monte Carlo-based computer models to show that selection pressure could affect the distribution of recombination hotspots along the chromosome. Close to the critical crossover rate, where genomes may switch between the Darwinian purifying selection or complementation of haplotypes, the distribution of recombination events and the force of selection exerted on genes affect the structure of chromosomes. The order of expression of genes and their location on chromosome may decide about the extinction or survival of competing populations.
