Crossover occurs during prophase i

WebThis pair of chromosomes are known as homologous chromosomes. ♦ Meiosis can be divided in two stages: meiosis I and meiosis II. It is in the prophase of meiosis I that crossing over of the chromosomes takes place, and the homologous chromosomes are separated into two daughter cells. In meiosis II, the sister chromatids are pulled apart … WebThe prophase stage of meiosis I have substages, leptotene, zygotene, pachytene, diplotene and diakinesis stages. Crossing over is a physical exchange of equal pieces of adjacent non-sister chromatids. When crossing over occurs, chromatids break and may be reattached to a different homologous chromosome.
