What's the difference between polymorphism and polymorphy?
Polymorphism
Definition:
(n.) Same as Pleomorphism.
(n.) The capability of assuming different forms; the capability of widely varying in form.
(n.) Existence in many forms; the coexistence, in the same locality, of two or more distinct forms independent of sex, not connected by intermediate gradations, but produced from common parents.

(19) As an extension to the variety of existing techniques using polymorphic DNA markers, the Random Amplified Polymorphic DNA (RAPD) technique may be used in molecular ecology to determine taxonomic identity, assess kinship relationships, analyse mixed genome samples, and create specific probes.
(20) We report that specific human (dC-dA)n.(dG-dT)n blocks are polymorphic in length among individuals and therefore represent a vast new pool of potential genetic markers.
Polymorphy
Definition:
(n.) Existence in many forms; polymorphism.
Example Sentences:
(1) The changes observed were alterations of the nucleus (fingerlike or fingerformed nuclei, nuclear invaginations, and intranuclear vesicular membrane bodies), changes of the mitochondries (number, polymorphy, and osmiophil bodies), as well as changes of lysosomes (myelin-shaped residual bodies).

(9) Also the size, polymorphy, and quantity of the detected antigens were in very good accordance with previously published data.
(10) The extreme polymorphy of the histological structure of the malignant melanoblastoma of the choroid, and the diverse forms of the tumor echogram stimulated the comparative investigation of such tumors in 22 cases.
(11) We saw alterations of the nucleus (finger-like or finger-formed nuclei, nuclear invaginations and intranuclear vesicular membranbodies), changes of the mitochondries (number, polymorphy and osmiophil bodies) as well as changes of lysosomes (myelinshaped residualbodies).
