Metamerism vs. Tagmatization — What's the Difference?

Metamerism may refer to: Metamerism (biology), in zoology and developmental biology, the property of having repeated segments, as in annelids Metamerism (color), in colorimetry, a kind matching of the colors that, based on differences in spectral power distribution, do not actually match In chemistry, the chemical property of having the same proportion of atomic components in different arrangements (obsolete, replaced with isomer). In organic chemistry, compounds having the same molecular formula but different number of carbon atoms (alkyl groups) on either side of functional group (e.g.

(zoology) The active process whereby tagmosis occurs

The condition of having the body divided into metameres, apparent in certain animals only in the early embryonic stages of development.

(biology) The segmentation of the body into similar discrete units.

(psychology) The matching of a perceived attribute between objects with differing physical attributes.

(colorimetry) The matching of apparent color of objects with different spectral power distributions.

(chemistry) Structural isomerism.

The symmetry of a metameric structure; serial symmetry; the state of being made up of metameres.

The state or quality of being metameric; isomerism due to different bonding patterns in two substances having the same molecular formula. Contrasted with steroisomerism or optical isomerism. Also, the relation or condition of metameric compounds.
