Purpose of Meiosis (Video)
Introduction
Meiotic Cell Division occurs exclusively in reproductive cells and consists of the process of meiosis followed by two cycles of specialized cell division which are similar to mitosis but not the same. The end product is four progeny (daughter) cells, each with half the number of chromosomes of the parent cell.
The following video is an introduction to meiosis.
Summary
- The end-product of meiosis is the production of (4) haploid gamete cells (sperm or egg) for sexual reproduction.
- The haploid gametes each contain only one copy of each chromosome.
- These gametes can be fused together (fertilization) to generate a new, diploid organism.
- Meiosis creates much of the genetic variation that exists between individuals.
