Full Answer

Independent assortment occurs during the formation of sex cells, or gametes. In organisms with cell nuclei, called eukaryotes, gametes are made during a specific type of cell division called meiosis.

When the new sex cells are produced during meiosis, they contain different combinations of chromosomes than were found in the original gamete. During reproduction, independent assortment helps each new organism become a unique individual.
