Some of these examples may show the adjective use. It seems unlikely that hitchhiking influences the two adjacent regions differently. A second reason is that indirect selection may be more efficient, whether it acts on favored alleles (genetic hitchhiking) or on deleterious mutations (background selection). What is even less clear is how prevalent hitchhiking is in species that are not models for genetic analysis. We consider several different evolutionary models including the neutral panmictic model, population subdivision, population size bottleneck, expansion and genetic hitchhiking. There are two scenarios under which hitchhiking might have this effect. Statistical tests of neutrality of mutations against population growth, hitchhiking and background selection. The low rates of substitution may imply that plant organelles are unlikely to experience frequent hitchhiking, due to insufficient rates of deleterious and advantageous mutation. Detecting a local signature of genetic hitchhiking along a recombining chromosome. At intermediate linkage, the decrease in caused by hitchhiking outweighs the increase caused by associative overdominance. Hitchhiking and associative overdominance at a microsatellite locus. The analysis is performed for five different alternative models (subdivision, expansion, contraction, bottleneck and hitchhiking) and for some arbitrary parameters. This is because of an inherent antagonism between hitchhiking and recombination. The hitchhiking effect on linkage disequilibrium between linked neutral loci. Power of neutrality tests to detect bottlenecks and hitchhiking. However, new models show that cultural hitchhiking can reduce genetic diversity if cultures evolve over time and there is moderate non-matrilineal transmission.
