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.

Pan-cancer landscape of homologous recombination deficiency

open access: yesNature Communications, 2020
Homologous recombination deficiency (HRD) results in impaired double strand break repair and is a frequent driver of tumorigenesis. Here, we develop a genome-wide mutational scar-based pan-cancer Classifier of HOmologous Recombination Deficiency (CHORD ...

Conserved Genetic Architecture Underlying Individual Recombination Rate Variation in a Wild Population of Soay Sheep (Ovis aries)

open access: yesGenetics, 2016
Meiotic recombination breaks down linkage disequilibrium (LD) and forms new haplotypes, meaning that it is an important driver of diversity in eukaryotic genomes.

Comparative gene mapping in Arabidopsis lyrata chromosomes 6 and 7 and A thaliana chromosome IV: evolutionary history, rearrangements and local recombination rates [PDF]

open access: yes, 2006
We have increased the density of genetic markers on the Arabidopsis lyrata chromosomes AL6 and AL7 corresponding to the A. thaliana chromosome IV, in order to determine chromosome rearrangements between these two species, and to compare recombination ...

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

CRISPR-directed mitotic recombination enables genetic mapping without crosses

open access: yesScience, 2016
Narrowing down genetic loci of interest Often it can be difficult to identify a gene or genetic region that underlies a specific trait. Traditional mapping relies on naturally occurring recombination events but can be limited in resolution by the natural

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.

Genealogy-based methods for inference of historical recombination and gene flow and their application in Saccharomyces cerevisiae [PDF]

open access: yes, 2012
Genetic exchange between isolated populations, or introgression between species, serves as a key source of novel genetic material on which natural selection can act.

Swine Influenza A Evolution via Recombination - Genetic Drift Reservoir

open access: yes, 2007
The looming influenza pandemic has focused attention^1-4^ on the rapid evolution of H5N1 and other human and avian serotypes. The basic tenets of influenza genetics^5^ define gradual changes as drifts caused by point mutations created by a polymerase ...
