Meiosis Definition. 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.
In biology, meiosis is the process by which one diploid eukaryotic cell divides to generate four haploid cells often called gametes. Meiosis is essential for sexual reproduction and therefore ...
Meiosis. Sexual reproduction in eukaryotes involves a form of cell division known as meiosis. It has several different stages that are carried out to let one diploid germ cell result in 4 haploid gametes. “Diploid” means that it’s going to have multiple copies of the genetic information, where “haploid” means it’s going to have one ...

What is Meiosis? Meiosis is a type of cell division which produces four daughter cells. Each of these cells consists of half the number of chromosomes present in the parent cell, as in the production of gametes and plant spores.
The steps of meiosis are very simple. When you break it down it's just two PMATI's in a row. Scientists say Meiosis I and Meiosis II, but it's just two PMATIs. The interphase that happens between the two processes is very short and the DNA is not duplicated. As we said, meiosis happens when it's time to reproduce.
Mitosis, a process of cell duplication, or reproduction, during which one cell gives rise to two genetically identical daughter cells. Strictly applied, the term is used to describe the duplication and distribution of chromosomes, the structures that carry the genetic information.
