WebProphase 1. The following ways in which meiosis II is different than meiosis I. Interkinesis doesn't involve the replication of chromosomes, whereas interphase does. Crossing-over doesn't occur in prophase II, whereas it does in prophase I. Cells in meiosis II are haploid and cells in meiosis I are diploid. WebAt several places along their length, non-sister chromatids (chromatids that belong to homologous chromosomes but are not identical sister chromatids) undergo a process called crossing over. The chromatids of homologous chromosomes cross over one another to hold the set of four chromatids together.
