During which phase of meiosis
WebMeiosis can be divided into nine stages. These are divided between the first time the cell divides (meiosis I) and the second time it divides (meiosis II): Meiosis I 1. Interphase: The DNA in the cell is copied resulting in two … WebCrossing over occurs during which stage of meiosis? Possible Answers: Metaphase I Prophase II Anaphase I Prophase I Correct answer: Prophase I Explanation: During prophase I homologous chromosomes will line up with one another, forming tetrads. During this lining up, DNA sequences can be exchanged between the homologous chromosomes.
