"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. " - During meiosis genes are divided into:

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.

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.

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.

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).
