WebIn meiosis, prophase is when crossing over and the exchange of DNA occurs between non sister chromatids. Next is metaphase where the chromosomes line up along the axis, and next is anaphase when the chromosomes are pulled apart, followed by metaphase where furrow forms, and lastly comes cytokinesis when the cell divides. WebThese two non-sister chromatid pair during the metaphase I of meiosis. When homologous chromosomes pair with each other, chromosomal crossover can occur between non-sister chromatids of each pair. Crossing over occurs from chiasmata during prophase I of meiosis. The process is called homologous recombination.
