WebScience Biology Compare and contrast meiosis and mitosis. Consider the following factors: Number of times DNA is replicated Number of cell divisions Number of daughter cells produced “Ploidy” of daughter cells Type of cells in which the process occurs Number and genetic make-up of chromosomes in parent cell compared to daughter cells. WebThe duplicated chromosomes align on a second spindle, and the sister chromatids separate to produce cells with a haploid DNA content. Meiosis thus consists of a single phase of DNA replication followed by two cell divisions. Four haploid cells are therefore produced from each cell that enters meiosis.
