Two important principles dictate the properties of a large proportion of structural chromosomal changes. The first principle is that any deviation from the normal ratio ... An inversion occurs when a chromosome breaks in two places and the region between the break rotates 180° before rejoining with the two end fragments.

An inversion is the rotation of a broken chromosome segment in such a way that it rejoins the chromosome in a reversed state, or is flipped, end to end. Inversions are usually characterized by whether the centromere is included in the inverted segment. ... Why chromosomal aberration occurs?
