WebMar 26, 2024 · Meiosis is the type of cell division that creates egg and sperm cells. Mitosis is a fundamental process for life. During mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells. Because this process is so critical, the steps of mitosis are carefully controlled by certain genes.

WebIn eukaryotic cells, or cells with a nucleus, the stages of the cell cycle are divided into two major phases: interphase and the mitotic (M) phase. During interphase, the cell grows and makes a copy of its DNA. During the mitotic (M) phase, the cell separates its DNA into two sets and divides its cytoplasm, forming two new cells. WebThe Process of Meiosis In contrast to mitosis, meiosisresults in the division of a diploidparental cell into haploidprogeny, each containing only one member of the pair of homologous chromosomesthat were present in the diploid parent (Figure 14.32).
