The exchange of corresponding segments of non-sister chromatids between a pair of homologous chromosomes during meiosis I is called crossing over.
In the field of biology, crossing over can be described as the process by which the non-sister chromatids of the homologous chromosomes exchange information or a segment of DNA with each other. It is due to this crossing over, that diversity is brought in individuals of a population.
The process of crossing over occurs during meiosis I and is the major factor for the biodiversity in organisms that reproduce by sexual methods. Crossing over occurs only during meiosis and not during mitosis.
