2020年6月11日 · Meiosis is the process in eukaryotic, sexually-reproducing animals that reduces the number of chromosomes in a cell before reproduction. Many organisms package these cells into gametes, such as egg and sperm.

Meiosis occurs in eukaryotic life cycles involving sexual reproduction, consisting of the cyclical process of growth and development by mitotic cell division, production of gametes by meiosis and fertilization.

2023年5月16日 · Meiosis is a cell division process where a single (parent) cell divides twice to produce four independent (daughter) cells, each having half the chromosomes as the original cell. The term ‘meiosis’ came from the Greek word ‘meiosis’, meaning ‘lessening’.

2023年10月21日 · In biology, meiosis is the process where a cell replicates DNA once but divides twice, producing four cells that have half the genetic information of the original cell. It is how organisms produce gametes or sex cells, which are eggs in females and sperm in males.

2025年3月26日 · meiosis, division of a germ cell involving two fissions of the nucleus and giving rise to four gametes, or sex cells, each possessing half the number of chromosomes of the original cell. A brief treatment of meiosis follows. For …

2023年8月3日 · Meiosis is a type of cell division in sexually reproducing eukaryotes, resulting in four daughter cells (gametes), each of which has half the number of chromosomes as compared to the original diploid parent cell.

2025年4月2日 · Meiosis is a type of cell division in sexually reproducing organisms that reduces the number of chromosomes in gametes (the sex cells, or egg and sperm). In humans, body (or somatic) cells are diploid, containing two sets of chromosomes (one from each parent).

2 天之前 · Meiosis is one of the most fascinating and essential biological processes that ensures the survival and diversity of life on Earth. It is a type of cell division that occurs in sexually reproducing organisms, responsible for producing reproductive cells or gametes (sperm and eggs in animals, pollen and ovules in plants).

2023年8月14日 · In the gametes, a different form of cell division occurs called “meiosis.” The outcome of meiosis is the creation of daughter cells, either sperm or egg cells, through reduction division which results in a haploid complement of chromosomes so that on joining with another sex cell at fertilization a new diploid chromosomal complement is ...

Meiosis is the process in which a single cell divides twice to form four haploid daughter cells. These cells are the gametes – sperms in males and egg in females. The process of meiosis is divided into 2 stages.
