Why do we have two copies of each chromosome? Short fast 1 minute answer

Human chromosomes have a very unique arrangement in the cell to guarantee the safe and healthy divide for transferring genes to the next generation of the cells.

These non-sex chromosomes are called autosomes. People usually have two copies of each chromosome. One copy is inherited from their mother (via the egg) and the other from their father (via the sperm). A sperm and an egg each contain one set of 23 chromosomes.
