Exempel på hitchhiking

• 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.

• This study assumed a hitchhiking event having not gone to fixation and could not exclude demographic hypotheses.

• 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.
