Meiosis Is a form of cell division that halves the number of chromosomes when forming specialized reproductive cells (gametes).

Chromosomal Disorders. Non-disjunction During meiosis, chromosomes are supposed to be divided evenly and into gametes. During meiosis, chromosomes are.

Mutations. Chromosomal Mutations Nondisjunction – Result of errors in Meiosis – Results in gametes with missing or extra chromosomes – Examples: Downs.
