What is Meiosis?
Meiosis is a type of Karyokinesis in which the nucleus divides to form four nuclei having half the number of chromosomes of the parent cell. It is a reductional division. Daughter nuclei formed are not identical to parent cells. Meiosis I is a reductional division because homologous chromosomes are segregated and thus chromosome number is reduced to half. Meiosis II is equational division and is very much similar to mitosis, chromatids of a chromosome are separated.
Between meiosis, I and meiosis II, a phase known as ‘interkinesis’ is present where centrosome replication occurs. Meiosis I involves the pairing of homologous chromosomes, crossing over between them, and their separation, leading to a reduction in chromosome number. Meiosis II is similar to mitosis, where sister chromatids are separated, resulting in the formation of four genetically non Identical haploid cells.
Difference Between Mitosis And Meiosis
Difference Between Mitosis And Meiosis: Meiosis and Mitosis cell division is crucial for sustaining life processes. Mitosis cell division produces two identical daughter cells with the same chromosome number, while meiosis produces four genetically different haploid cells for sexual reproduction.
Mitosis takes part in growth, repair, and asexual reproduction, on the other hand, meiosis is essential for sexual reproduction, producing sperm and egg cells for genetic diversity. This article provides a difference between mitosis and meiosis, a brief introduction to cell division, an overview of mitosis and meiosis, and their significance.
