Allopolyploidization increases genetic recombination in the ancestral diploid D genome during wheat evolution

open access: yesCrop Journal, 2022
Genetic recombination produces new allelic combinations, thereby introducing variation for domestication. Allopolyploidization has increased the evolutionary potential of hexaploid common wheat by conferring the advantages of heterosis and gene ...

Recombination in enteroviruses is a biphasic replicative process involving the generation of greater-than genome length 'imprecise' intermediates [PDF]

open access: yes, 2014
Recombination in enteroviruses provides an evolutionary mechanism for acquiring extensive regions of novel sequence, is suggested to have a role in genotype diversity and is known to have been key to the emergence of novel neuropathogenic variants of ...

The effects of recombination rate on the distribution and abundance of transposable elements [PDF]

open access: yes, 2008
Transposable elements (TEs) often accumulate in regions of the genome with suppressed recombination. But it is unclear whether this pattern reflects a reduction in the efficacy of selection against deleterious insertions or a relaxation of ectopic ...

Regional differences in recombination hotspots between two chicken populations [PDF]

open access: yes, 2010
Background Although several genetic linkage maps of the chicken genome have been published, the resolution of these maps is limited and does not allow the precise identification of recombination hotspots. The availability of more than 3.2 million SNPs in

Copy number variation, chromosome rearrangement, and their association with recombination during avian evolution [PDF]

open access: yes, 2010
Chromosomal rearrangements and copy number variants (CNVs) play key roles in genome evolution and genetic disease; however, the molecular mechanisms underlying these types of structural genomic variation are not fully understood.

Assessing by Modeling the Consequences of Increased Recombination in Recurrent Selection of Oryza sativa and Brassica rapa

open access: yesG3: Genes, Genomes, Genetics, 2019
Meiotic recombination generates genetic diversity but in most species the number of crossovers per meiosis is limited. Previous modeling studies showed that increasing recombination can enhance response to selection.

Linkage disequilibrium and recombination rate estimates in the self-incompatibility region of Arabidopsis lyrata [PDF]

open access: yes, 2007
Genetic diversity is unusually high at loci in the S-locus region of the self-incompatible species of the flowering plant, Arabidopsis lyrata, not just in the S loci themselves, but also at two nearby loci.

A high-resolution single nucleotide polymorphism genetic map of the mouse genome.

open access: yesPLoS Biology, 2006
High-resolution genetic maps are required for mapping complex traits and for the study of recombination. We report the highest density genetic map yet created for any organism, except humans.

Multiple mating but not recombination causes quantitative increase in offspring genetic diversity for varying genetic architectures. [PDF]

open access: yesPLoS ONE, 2012
Explaining the evolution of sex and recombination is particularly intriguing for some species of eusocial insects because they display exceptionally high mating frequencies and genomic recombination rates. Explanations for both phenomena are based on the

Sequence diversity and potential recombination events in the coat protein gene of Apple stem pitting virus. [PDF]

open access: yes, 2011
The variability of the Apple stem pitting virus (ASPV) coat protein (CP) gene was investigated. The CP gene of ten virus isolates from apple and pear trees was sequenced.
