Homeosis refers to a structure, "A," or part of "A," developing at the site of structure "B" (Sattler, 1988, 1994).
The best-known example of homeosis in plants is the replacement of one kind of floral organ by another.
A good example of partial homeosis is the development of male flowers on the heteromorphic inflorescences in Neptunia pubescens (Leguminosae).
Although most studies of homeosis in plants focus on its role in floral morphological evolutionary changes (e.
In many cases, the developmental changes explained with heterochrony can also be interpreted by homeosis (Jordan & Anthony, 1993).
Homeosis and heterotopy are therefore overlapping concepts: complete homeosis is simply heterotopy.
Other development-related mechanisms, such as homeosis and heterotopy, are important causes of evolutionary morphological change.
