So crossing over not only provides a mechanism for genetic recombination during meiosis but also provides a means of repairing damage to the genome. ... Crossing Over and Genetic Recombination in Meiosis ... Crossing over occurs between equivalent portions of two nonsister chromatids.

While they are pressed together, the chromosomes may break, and each may swap a portion of its genetic material for the matching portion from its mate. This form of recombination is called crossing-over. When the chromosomes glue themselves back together and separate, each has picked up new genetic material from the other.

Chromosomal crossover (or crossing over ) is the exchange of genetic material between homologous chromosomes. This often occurs during prophase 1 of meiosis in a process called synapsis. Synapsis b...

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.
