Inversion

inversion

A chromosome having the standard sequence of regions labelled 1 to 7, inclusive, is shown on the left. If a segment labelled 2 and 3 becomes inverted then the new configuration shown on the right is called an inversion. When the standard and inverted chromosomes pair with one another the result is a chromosome loop as shown in the lower part of the diagram.
