In general, the term inversion refers to the reversal of state, form, position, direction, order, or course. In biology, particularly in anatomy, the term inversion is used to refer to the movement of sole towards the median plane. In genetics, inversion is a type of large-scale mutation.

In evolutionary developmental biology, inversion refers to the hypothesis that during the course of animal evolution, the structures along the dorsoventral (DV) axis have taken on an orientation opposite that of the ancestral form.. Inversion was first noted in 1822 by the French zoologist Étienne Geoffroy Saint-Hilaire, when he dissected a crayfish (an arthropod) and compared it with the ...
Definition of inversion, a movement. The term inversion may used to describe movement at a joint e.g. how two body parts move in relation to each other. This or related words may also be used to describe the action of certain muscles that cause such movement.
There are two types of chromosomal inversions. They are the pericentric inversion and the paracentric inversion. A pericentric inversion is one that includes the centromere and the break point occurs in each arm. In paracentric inversion, the inversion of the chromosome involves the centromere and both breaks occur in one arm of the chromosome.
Inversion definition, an act or instance of inverting. See more. music. the process or result of transposing the notes of a chord (esp a triad) such that the root, originally in the bass, is placed in an upper part.
Inversion in biology is the breaking of a chromosome in two places and the subsequent reordering re-insertion of the chromosome DNA. Inversions are divided into pericentric and paracentric types based on whether the centromere was involved.
effects depend on when it occurs; if during mitotic division- only some cells will be affected and create individuals with Mosaicism (like a mosaic some of the cells contain the normal number of chromosomes and some contain an abnormal number) effects will depend on the ratio and location of abnormal cells of the two cell populations.
