Prophase ii summary
Webb18 aug. 2024 · Prophase 2 Each cell formed during meiosis I now divides again. A spindle forms in each of the new cells. Metaphase 2 Individual chromosomes line up at the equator of each cell, with the centromeres attached to the spindle fibres. Anaphase 2 The spindle fibres start to contract. WebbCells remain diploid at the end of telophase I, but are haploid at the end of telophase II. Daughter cells form a cell plate to divide during telophase I, but divide by cytokinesis during telophase II. Cells enter interphase after telophase I, but not after telophase II.
