Crossing over is advantageous because it brings about variation.
* The exchange of genetic material between the non- sister chromatids of a pair of homologous chromosomes during meiosis.
It takes place during the pachytene stage of prophase I of meiosis.
* The sites at which this exchange takes place, it forms chiasmata.
* It is an important step that brings about recombination and thereby variation by exchanging of genetic material.
