....6 cM/Mb (Hemmer et al. 2020), and D. melanogaster of 2.5 cM/Mb (Comeron et al. 2012). However, experimental studies of Drosophila have rarely looked at variation in -wide recombination rates in natural populations of outbred individuals, and wild populations may differ systematically from populations...

...lower in primates and plants (Boyko et al. 2008; Eyre-Walker and Keightley 2009; Gossmann et al. 2010). In these latter species, formal tests have been unable to reject the hypothesis that α is zero (i.e., no positive selection) (Boyko et al. 2008; Foxe et al. 2008; Eyre-Walker and Keightley 2009...

...of recombination is essential since this parameter is considered to affect levels of genetic variability, the efficacy of selection, and the design of association and linkage mapping studies. However, there is limited knowledge about the factors governing recombination rate variation. We genotyped 1920 single...

...the fates of new alleles in populations (Fisher 1930; Muller 1932; Hill and Robertson 1966; Felsenstein 1974). Levels of linkage disequilibrium across s and the efficacy of natural selection are expected to vary among taxa as a function of recombination rate. Interspecific comparisons of recombination rates...

...) that recombine infrequently. Furthermore, human orthologs of mouse genes, which, when disrupted, result in pre- or postnatal lethality, are unusually depleted in CNVs. Together, these findings support a model of reduced purifying selection (Hill–Robertson interference) within copy number variable regions...

...of the species. The role of natural selection in these processes is particularly interesting to understand. Recently, Locke et al. (2011) added the orangutan to the list of fully sequencedprimates, and this opens the investigationof a new time epoch in primate evolution. Whole- analysis of the fiveway alignment...

Are they primarily driven by changes in the environment, which alter the nature of selective pressures at a subset of genes, or by demographic changes that shape the efficacy of purifying selection across the ?

...to the proposal that recombination facilitates adaptive evolution, by enhancing the efficacy of natural selection on molecular variants (e.g., Marais and Charlesworth 2003 ). Recently, the role of recombination in neutral evolution has also drawn great interest (e.g., Perry and Ashworth 1999 ; Fullerton et al...

...with social life. By increasing the efficiency of natural selection (Felsenstein 1974; Comeron et al. 2008), high recombination rates may promote the evolution of caste-specific genes (Kent et al. 2012; Kent and Zayed 2013). Studies in Drosophila have suggested a link between recombination and the efficacy...
