Most of the time when people refer to "cell division", the process of making new body cells. Meiosis is the type of division that creates egg and sperm cells. Miosis is a fundamental process in life.

Each rod represents a chromatid, and DNA replication results in two sister chromatids joined at their centromeres. Mitosis separates the sister chromatids. This unique sequence of 2-cell division produces haploid gametes from diploid germline cells. It starts with a diploid cell that has undergone chromosomal DNA content. Two successive divisions with no other DNA replication results in 4 haploid gametes.

because of recombination and independent assortment in meiosis, each gamete contains a different set of DNA. This produces a unique combination of genes in the resulting zygote. Recombination or crossing over occurs during the prophase. June 10, 2011. Homologous chromosomes 1. inherit from each parent pair along their lengths, gene by gene breaks occur along the chromosomes, and they have to rejoin, trading some of their genes. The chromosomes now have genes in a unique combination.

Meiosis is the form of nuclear cell division resulting in daughter cells with one-half the chromosome numbers as the original cell. In organisms, the results are diploid; the end result is haploid cells. Each daughter cell gets one complete set of chromosomes, i.e. one of each homologous pair of chromosomes. In humans, this is reduced from 46-23.
The germ cell undergoes meiosis to give rise to sperm and eggs. Joining the sperm and egg together during fertilization returns the number of chromosomes to 46.
Meiosis produces four genetically different haploid cell chromosomes not yet visible in DNA has been duplicated or replicated. Prophase crossing over and recombination of Homologous chromosomes [each consisting of two sister chromatids] appear together as pairs. Tetrad or bivalent is the structure in which segments of chromosomes are exchanged between non-sister chromatids at crossover points known as chiasmata [crossing over]. Metaphase chromosomes adjust on the metaphase plate. Chromosomes are still intact and arranged as pair of homologues [bivalent].

The events that occur in Meiosis but not in Mitosis include homologous chromosomes pairing up, crossing over and lining up along the metaphase plate in Tetrads.

It produces a gamete carrying mixed chromosomes. Gametes contain half the number of regular chromosomes in a diploid somatic cell. Even though genes are found on the same chromosome or linked, genes are not randomly assorted. A crossover that takes place during meiosis allows such genes to rearrange. June 20, 2022.
