Genome-Wide Association Study of Meiotic Recombination Phenotypes
G3: Genes, Genomes, Genetics, 2016 Meiotic recombination is an essential step in gametogenesis, and is one that also generates genetic diversity. Genome-wide association studies (GWAS) and molecular studies have identified genes that influence of human meiotic recombination.

Evolutionary Computation, 1998 Problem-specific knowledge is often implemented in search algorithms using heuristics to determine which search paths are to be explored at any given instant. As in other search methods, utilizing this knowledge will more quickly lead a genetic algorithm (GA) towards better results.

ZIP4 is required for normal progression of synapsis and for over 95% of crossovers in wheat meiosis
Frontiers in Plant Science, 2023 Tetraploid (AABB) and hexaploid (AABBDD) wheat have multiple sets of similar chromosomes, with successful meiosis and preservation of fertility relying on synapsis and crossover (CO) formation only taking place between homologous chromosomes.

Crossover Interference, Crossover Maturation, and Human Aneuploidy
BioEssays, 2019 A striking feature of human female sexual reproduction is the high level of gametes that exhibit an aberrant number of chromosomes (aneuploidy). A high baseline observed in women of prime reproductive age is followed by a dramatic increase in older women.

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2019 Background Crossover dilutes treatment effect and reduces statistical power of intention‐to‐treat analysis. We examined incidence and impact on cardiac surgery randomized controlled trial (RCT) outcomes of crossover from experimental to control ...

Tackling Plant Meiosis: From Model Research to Crop Improvement
Frontiers in Plant Science, 2018 Genetic engineering and traditional plant breeding, which harnesses the natural genetic variation that arises during meiosis, will have key roles to improve crop varieties and thus deliver Food Security in the future. Meiosis, a specialized cell division

Crossover from random-exchange to random-field critical behavior in Ising models [PDF]
, 2003 We compute the crossover exponent $\phi$ describing the crossover from the random-exchange to the random-field critical behavior in Ising systems. For this purpose, we consider the field-theoretical approach based on the replica method, and perform a six-
