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.

Recombination and Genetic Diversity

Trends in Computational and Applied Mathematics, 2012
In this paper we present a spatial stochastic model for genetic recombination, that answers if diversity is preserved in an infinite population of recombinating individuals distributed spatially.

Recombination and Its Impact on the Genome of the Haplodiploid Parasitoid Wasp Nasonia [PDF]

, 2010
Homologous meiotic recombination occurs in most sexually reproducing organisms, yet its evolutionary advantages are elusive. Previous research explored recombination in the honeybee, a eusocial hymenopteran with an exceptionally high genome-wide ...

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.

Lineage specific recombination rates and microevolution in Listeria monocytogenes [PDF]

, 2008
Background: The bacterium Listeria monocytogenes is a saprotroph as well as an opportunistic human foodborne pathogen, which has previously been shown to consist of at least two widespread lineages (termed lineages I and II) and an uncommon lineage ...

Mapping of meiotic recombination in human preimplantation blastocysts

G3: Genes, Genomes, Genetics, 2023
Recombination is essential for physical attachments and genetic diversity. The Han Chinese population is the largest ethnic group worldwide, therefore, the construction of a genetic map regarding recombination for the population is essential.

Targeted recombination of homologous chromosomes using CRISPR‐Cas9

FEBS Open Bio, 2023
CRISPR mutagenesis is an efficient way to disrupt specific target genes in many model organisms. We previously devised a targeted CRISPR recombination method to generate intragenic recombinants of alleles in Drosophila.
