Meiosis begins with a diploid cell, which contains two copies of each chromosome, termed homologs. First, the cell undergoes DNA replication, so each homolog now consists of two identical sister chromatids. Then each set of homologs pair with each other and exchange genetic information by homologous recombination often leading to physical connections (crossovers) between the homologs. In the ...
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'.
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 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.
Meiosis, division of a germ cell involving two fissions of the nucleus and giving rise to four gametes, or sex cells, each with half the number of chromosomes of the original cell. The process of meiosis is characteristic of organisms that reproduce sexually and have a diploid set of chromosomes in the nucleus.
Meiosis is the formation of egg and sperm cells. In sexually reproducing organisms, body cells are diploid, meaning they contain two sets of chromosomes (one set from each parent).
Meiosis, on the other hand, is used for just one purpose in the human body: the production of gametes —sex cells, or sperm and eggs. Its goal is to make daughter cells with exactly half as many chromosomes as the starting cell.

The body is made up of trillions of somatic cells with the capacity to divide into identical daughter cells facilitating organismal growth, repair, and response to the changing environment. This process is called "mitosis." 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 ...
