GENETIC FACTORS INFLUENCING CROSSING-OVER FREQUENCY IN NEUROSPORA [PDF]
DIFFERENT crosses involving the same marked region in Neurospora crassa may yield markedly different frequencies of recombinants. It has been suggested that the fluctuations in recombination frequency result from inherent differences between the various wild-type strains from which the stocks descended (BARRATT 1954; FROST 1961). However, the nature of

Contribution of crossing over to genetic variance in maize and wheat populations
Crossing 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.).

INTERFERENCE IN GENETIC CROSSING OVER AND CHROMOSOME MAPPING
ABSTRACT This paper proposes a general model for interference in genetic crossing over. The model assumes serial Occurrence of chiasmata, visualized as a renewal process along the paired (or pairing) chromosomes. This process is described as an underlying Poisson process in which the Ist, n + 1th, 2n + 1th, etc., events are to be ...

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.

A high-resolution crossover landscape in Drosophila santomea reveals rapid and concerted evolution of multiple properties of crossing over control. [PDF]
Crossing over is a fundamental process in sexually reproducing species, ensuring proper chromosome segregation during gamete formation and generating new allelic combinations that enhance adaptation. Despite its essential role, genes involved in crossing

Selection strategies for the development of maize introgression populations. [PDF]
Introgression libraries are valuable resources for QTL detection and breeding, but their development is costly and time-consuming. Selection strategies for the development of introgression populations with a limited number of individuals and high ...

Exo1 protects DNA nicks from ligation to promote crossover formation during meiosis.
In most sexually reproducing organisms crossing over between chromosome homologs during meiosis is essential to produce haploid gametes. Most crossovers that form in meiosis in budding yeast result from the biased resolution of double Holliday junction ...
