Control of meiotic crossing over in plant breeding. [PDF]
Vavilovskii Zhurnal Genet Selektsii, 2023 Meiotic crossing over is the main mechanism for constructing a new allelic composition of individual chromosomes and is necessary for the proper distribution of homologous chromosomes between gametes.

DNA polymerase theta suppresses mitotic crossing over. [PDF]
PLoS Genet, 2021 Polymerase theta-mediated end joining (TMEJ) is a chromosome break repair pathway that is able to rescue the lethality associated with the loss of proteins involved in early steps in homologous recombination (e.g., BRCA1/2). This is due to the ability of

Sex without crossing over in the yeast Saccharomycodes ludwigii. [PDF]
Genome Biol, 2021 Background Intermixing of genomes through meiotic reassortment and recombination of homologous chromosomes is a unifying theme of sexual reproduction in eukaryotic organisms and is considered crucial for their adaptive evolution.

Positive Selection and Functional Divergence at Meiosis Genes That Mediate Crossing Over Across the Drosophila Phylogeny. [PDF]
G3 (Bethesda), 2019 Meiotic crossing over ensures proper segregation of homologous chromosomes and generates genotypic diversity. Despite these functions, little is known about the genetic factors and population genetic forces involved in the evolution of recombination rate

Crossing over...Markov meets Mendel. [PDF]
PLoS Comput Biol, 2012 Chromosomal crossover is a biological mechanism to combine parental traits. It is perhaps the first mechanism ever taught in any introductory biology class.

Contribution of crossing over to genetic variance in maize and wheat populations. [PDF]
Plant GenomeCrossing over breaks linkages and leads to a wider array of allele combinations. My objective was to assess the contribution of crossing over to genetic variance (VG) in maize (Zea mays L.) and wheat (Triticum aestivum L.).

Human Cell Assays for Synthesis-Dependent Strand Annealing and Crossing over During Double-Strand Break Repair. [PDF]
G3 (Bethesda), 2017 DNA double-strand breaks (DSBs) are one of the most deleterious types of lesions to the genome. Synthesis-dependent strand annealing (SDSA) is thought to be a major pathway of DSB repair, but direct tests of this model have only been conducted in budding

Genetic Background, Maternal Age, and Interaction Effects Mediate Rates of Crossing Over in Drosophila melanogaster Females. [PDF]
G3 (Bethesda), 2016 Meiotic recombination is a genetic process that is critical for proper chromosome segregation in many organisms. Despite being fundamental for organismal fitness, rates of crossing over vary greatly between taxa.
