- How do telophase I and telophase II differ during meiosis in animal cells? Cells 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 Chromosomes can remain condensed at the end of telophase k but decondense after telophase II.2. The amount of DNA in a Drosophila melanogaster somatic cell equals 8 during G1 of interphase, how much DNA is present in the cell during each phase of mitosis and meiosis?
