WebGametes Are Produced by Two Meiotic Cell Divisions. The meiotic cell division just described—referred to as division I of meiosis—does not produce cells with a haploid amount of DNA. Because the sister chromatids behave as a unit, each daughter cell of this division inherits two copies of one of the two homologs. Web15 sep. 2024 · September 15, 2024 by Alexander Johnson. Meiosis is responsible for the formation of sex cells or gametes that are responsible for sexual reproduction. It activates the genetic information for the development of sex cells and deactivates the sporophytic information. It maintains the constant number of chromosomes by halving the same.

WebMeiosis is a type of cell division that starts with a diploid, 2n cell. The process includes two chromosome divisions and produces four haploid, n cells.
