noun, plural: inversions
(biogeology) The folding back of strata upon themselves resulting in a seemingly order of succession
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. Mutation is a change in the nucleotide sequence of a gene or a chromosome. Chromosomal inversions are a rearrangement within the chromosome and are of two types: pericentric (i.e. chromosomal inversions including the centromere) and paracentric (i.e. inversions that do not include the centromere).
In zoology, inversion pertains to the switching from one sex to the opposite in certain animal species. Sexual inversion, per se, is an archaic term used to mean taking on the gender role of the opposite sex.
