Be sure you show the correct number of chromosomes at each stage as well as the correct number of cells at the end of the process. 2. What kind of cells are produced by mitosis? WebMeiosis employs many of the same mechanisms as mitosis. However, the starting nucleus is always diploid and the nuclei that result at the end of a meiotic cell division are haploid. To achieve this reduction in chromosome number, meiosis consists of one round of chromosome duplication and two rounds of nuclear division.
