WebJan 2, 2012 · Cytokinesis. Cytokinesis is technically a separate set of events to mitosis. It describes the series of events seen when the cell splits into two. This process starts as a cleavage furrow between the cells, making it look like the figure 8. This furrow extends until the whole cell has split.

WebThe somatic cell cycles discussed so far in this chapter result in diploid daughter cells with identical genetic complements. Meiosis, in contrast, is a specialized kind of cell cycle that reduces the chromosome number by half, resulting in the production of haploid daughter cells.
