Inversion

• When a segment of a chromosome breaks off.

• When a segment of a chromosome breaks off, flips, and reattaches.

• When a segment of a chromosome is copied or doubles.

• When a segment of a chromosome breaks and attaches to a non homologous chromosome.

• When entire chromosomes don't separate evenly during meiosis.
