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. WebMeiosis ensures that the chromosome number remains constant generation after generation. B) Meiosis ensures that each generation has a different genetic makeup than the previous one. C) Meiosis ensures that each newly formed daughter cell receives the same number and kinds of chromosomes. D) Meiosis results in four daughter cells. E)
