WebThe Process of Meiosis. In contrast to mitosis, meiosis results in the division of a diploid parental cell into haploid progeny, each containing only one member of the pair of homologous chromosomes that were present in the diploid parent (Figure 14.32).This reduction in chromosome number is accomplished by two sequential rounds of nuclear … WebMeiosis.
