Mitosis vs. Meiosis Biology Dictionary

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.

WebIntroduction: Meiosis is a type of cell division that produces gametes – sperm and egg cells – in sexually reproducing organisms. Unlike mitosis, which produces identical daughter cells, meiosis results in cells that have half the number of chromosomes as the parent cell. This is important because when the sperm and egg cells fuse during WebThere are two types of cell division. Mitosis produces two identical diploid daughter cells. Meiosis produces four non-identical haploid gametes (sex cells).

WebCells undergo through meiosis I to meiosis II without the replication of the genetic material. It is important to note that the cells that undergo meiosis II are the daughter cells produced during meiosis I. Meiosis II is shorter than meiosis I but still is divided into four stages: prophase II, metaphase II, anaphase II, and telophase II. WebDuring meiosis I, homologous chromosomes pair up with each other. When the homologs are divided into daughter cells, the chromosomes are sorted randomly into daughter cells. If alleles of...

WebDec 18, 2016 · This is known as an equational division since the duplicated chromosomes are equally divided and the genetic content is not changed. By contrast, meiosis has two divisions: a reductional division that decreases the genetic content, followed by an equational division that separates sister chromatids just like mitosis.

WebMeiosis: Telophase l The cell divides into two cells during telophase I (Figure 11). The bundle of chromosomes may have a nuclear envelope develop around them. The germline cells in some organisms such as human females, go through the first four stages of meiosis prior to birth. The germline cells remain at telophase I for some time.

WebSince cell division occurs twice during meiosis, one starting cell can produce four gametes (eggs or sperm).
