The difference of prophase i & ii
WebThe process is split into meiosis I and meiosis II, and both meiotic divisions have multiple phases. Meiosis I is a type of cell division unique to germ cells, while meiosis II is similar … WebProphase II is much shorter than prophase I (Meiosis I), primarily because no further genetic reassortment, or crossover, takes place. While the chromosomes uncoiled and decondensed in telophase I, in prophase II they condense again. The nuclear membrane disintegrates, and the spindle fibers reform. Sister chromatids grow kinetochores. Metaphase II

WebJun 11, 2024 · Prophase II Prophase II resembles prophase I. The nuclear envelopes disappear and centrioles are formed. Microtubules extend across the cell to connect to the kinetochores of individual chromatids, connected by centromeres. The chromosomes begin to get pulled toward the metaphase plate. Metaphase II
