}The successful domestication of wild plants has been one of the most important human accomplishments of the last 10,000 yr. Though our empirical knowledge of the genetic mechanisms of plant domestication is still relatively limited, there exists a large body of theory that offers a host of hypotheses on the genetics of domestication. Two of these that have not been addressed concern the role of recombination in the process of domestication. The first predicts an increase in recombination rate…

Quantitative trait loci and the study of plant domestication

Some of the recent work on the quantitative genetics of plant domestication are reviewed, some of the common trends found in this literature are identified, and some novel interpretations of the data that is currently available are offered.
The contribution of recombination to heterozygosity differs among plant evolutionary lineages and life-forms
- BiologyBMC Evolutionary Biology
- 2009
The results illustrate how both common ancestry and life-history traits have to be taken into account for understanding the evolution of genetic diversity and genomic rates of recombination across plant species, and highlight the relevance of species life forms to explain general levels of diversity and recombination.
Strong artificial selection in domestic mammals did not result in an increased recombination rate.
- BiologyMolecular biology and evolution
- 2015
The data indicate that strong directional selection did not result in changes in recombination in domestic mammals, and that both upper and lower bounds for crossover rates may be tightly regulated.
Recombination and speciation
- BiologyMolecular ecology
- 2005
It is argued that ideas about the role of recombinations in speciation should be considered in the context of the variability of recombination rates and patterns more generally and that genic as well as chromosomal causes of restricted recombination should be consideration.
Connecting theory and data to understand recombination rate evolution
- BiologyPhilosophical Transactions of the Royal Society B: Biological Sciences
- 2017
It is argued that efforts to integrate the rich bodies of empirical and theoretical work on recombination rate are crucial to moving this field forward, and new directions for the development of theory and the production of data are provided that will jointly close this gap.
Variation in genomic recombination rates among animal taxa and the case of social insects
- BiologyHeredity
- 2007
It is found that among the higher eukaryotes exceptionally high rates are found in social Hymenoptera, compatible with current hypotheses suggesting that sociality in insects strongly selects for increased genotypic diversity in worker offspring to meet the demands of a sophisticated caste system or to mitigate against the effects of parasitism.
Evolution of recombination in eutherian mammals: insights into mechanisms that affect recombination rates and crossover interference
- Biology, Environmental ScienceProceedings of the Royal Society B: Biological Sciences
- 2013
This work analyses the recombination features from species representing the major eutherian taxonomic groups Afrotheria, Rodentia, Primates and Carnivora to better understand the dynamics of mammalian recombination and suggests a phylogenetic component in recombination rates (RRs).

The limits of selection during maize domestication

The results help to explain why maize is such a variable crop, and suggest that maize domestication required hundreds of years, and confirm previous evidence that maize was domesticated from Balsas teosinte of southwestern Mexico.

It is suggested that those colonizing species which had more open, or at least more flexible, recombination systems were, in a sense, pre-adapted to domestication.
Mammalian chiasma frequencies as a test of two theories of recombination

It is concluded that crossing-over may function to combat antagonists with short generation times but does not function to reduce sib competition, and Chromosome number is selectively neutral with respect to these factors.

The study showed that the crop species were a random selection as far as ploidy level is concerned and that domestication did not appear to have favored polyploid over diploid genomes or vice versa.

The results from modifier models indicate that decreased recombination rates are usually favored when the population is initially near a polymorphic equilibrium with linkage disequilibrium, and increased recombination may be favored under certain conditions, provided that there is negative epistasis among alleles.
