Human somatic cells have 46 chromosomes consisting of two sets of 22 homologous chromosomes and a pair of nonhomologous sex chromosomes. This is the 2n, or diploid, state. Human gametes have 23 chromosomes or one complete set of chromosomes. This is the n, or haploid, state. Genes are segments of DNA that code for a specific protein or RNA molecule.

The cell cycle is an orderly sequence of events that describes the stages of a cell’s life from the division of a single parent cell to the production of two new daughter cells. The mechanisms involved in the cell cycle are highly regulated.

Mitosis produces two genetically identical diploid cells for growth and replacement, while meiosis results in four genetically diverse haploid cells essential for sexual reproduction.

It can occur naturally through errors in gamete formation or be induced artificially. Polyploidy can lead to speciation, with hybrids often sterile while polyploid plants remain fertile. Although rare in animals, some instances, such as a tetraploid rat, have been recorded.

It highlights the importance of checkpoints to prevent errors, which, if present, can lead to chromosomal abnormalities such as monosomy, often lethal, and trisomy, which can result in conditions like Down syndrome.
