These results predict that the rate of synonymous substitution should be higher in regions of lowrecombination. Two studies have found increased differentiation in a subdivided population in regions of lowrecombination. However, in regions showing permanently lowrecombination rate, recurrent selective events remove most of the variability and make it difficult to distinguish the two hypotheses. This is especially likely if the marker is in a region with lowrecombination. As a consequence, regions of high recombination should harbour more polymorphism than regions of lowrecombination. It is also encouraging for comparing the evolution of genes in regions with high and lowrecombination frequencies. According to the foregoing spectral properties, the amplitude of the low-frequency autooscillations will tend to increase together with the frequency of the allele for lowrecombination. For nearly any method, estimating very high or very lowrecombination rates is difficult, because the data necessary to discriminate between multiple extreme values of r are usually lacking. There were significantly fewer recombination events in the closer than the more distant region, supporting the above prediction, but showing that the lowrecombination region is very limited in size. Hybrid recombinational portraits for six markers along the second chromosome also reflected the presence of a region with dramatically lowrecombination rate. Lowrecombination reduces this ability because favourable mutations have a high probability of occurring in bad genomes, from which they can be effectively freed only by high recombination. Other things being equal, these effects should be most pronounced in genomic regions with low recombination, if loci involved in local adaptation are present in all regions. Third, the banding pattern in regions of lowrecombination (the base of the autosomes and the fourth chromosome) is more difficult to interpret, so fixations might be overlooked. One technique is to compare levels of nucleotide diversity in regions of lowrecombination, where the models differ appreciably in their predictions.

This process seems to be dominated by genetic drift resulting from small population size, low recombination rates, and high mutation rates, as opposed to selection for smaller genomes.

Measured coalescent effective population sizes vary between genes in the same population, being low in genome areas of lowrecombination and high in genome areas of high recombination.
