Similarity in recombination rate estimates highly correlates with genetic differentiation in humans. [PDF]

PLoS ONE, 2011
Recombination varies greatly among species, as illustrated by the poor conservation of the recombination landscape between humans and chimpanzees. Thus, shorter evolutionary time frames are needed to understand the evolution of recombination.

Genome-wide recombination variation in biparental segregating and reciprocal backcross populations provides information for introgression breeding in Brassica napus

Crop Journal, 2023
Variation in patterns of recombination in plant genomes provides information about species evolution, genetic diversity and crop improvement. We investigated meiotic crossovers generated in biparental segregating and reciprocal backcross populations of ...

Genetic variants in REC8, RNF212, and PRDM9 influence male recombination in cattle. [PDF]

PLoS Genetics, 2012
We use >250,000 cross-over events identified in >10,000 bovine sperm cells to perform an extensive characterization of meiotic recombination in male cattle.

Genetic Recombination and Molecular Evolution [PDF]

Cold Spring Harbor Symposia on Quantitative Biology, 2009
Reduced rates of genetic recombination are often associated with reduced genetic variability and levels of adaptation. Several different evolutionary processes, collectively known as Hill-Robertson (HR) effects, have been proposed as causes of these correlates of recombination.

Genetic variation in recombination rate in the pig

Genetics Selection Evolution, 2021
Background Meiotic recombination results in the exchange of genetic material between homologous chromosomes. Recombination rate varies between different parts of the genome, between individuals, and is influenced by genetics.

Variation and genetic control of individual recombination rates in Norwegian Red dairy cattle

Journal of Dairy Science, 2023
: Meiotic recombination is an important evolutionary mechanism that breaks up linkages between loci and creates novel haplotypes for selection to act upon.

SUMOylation of Rad52-Rad59 synergistically change the outcome of mitotic recombination [PDF]

, 2016
Homologous recombination (HR) is essential for maintenance of genome stability through double-strand break (DSB) repair, but at the same time HR can lead to loss of heterozygosity and uncontrolled recombination can be genotoxic.

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

, 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 ...
