Brit.

/ˌparədʒᵻˈnɛtɪk/, U.S.

/ˈˌpɛrədʒəˈnɛdɪk/

Origin: Formed within English, by derivation. Etymons: para- prefix¹, -genetic comb. form.

Etymology: < para- prefix¹ + -genetic comb. form. In senses 1 and 2a after paragenesis n.

1. Geology. Relating to or involving paragenesis (paragenesis n. 1a); (of minerals) co-occurring in the same deposit; (also) spec. denoting or relating to the sequence in which a suite of minerals crystallize.

1883 M. F. Heddle in Encycl. Brit. XVI. 367/1 Twins [sc. crystals] have..been divided into ‘paragenetic’ and ‘metagenetic’. The first term is applied to the ordinarily occurring twins, in which the compound structure is supposed..to have been compound in its very origin.

1912 Econ. Geol. 7 641 The present tendency is to base varieties upon occurrence, association, or origin, or, in short, upon paragenesis; hence, the term paragenetic varieties.

1967 Science 21 July 307/3 This occurrence strongly supports the alteration of glass to alkali-rich zeolite to analcime as the paragenetic sequence of alteration of tuffaceous rocks deposited in ancient Lake Gosiute.

2. Biology.

†a. Of or relating to paragenesis (paragenesis n. 2a). Cf. paragenesic adj. rare. Perhaps disused.

ΚΠ

1890 Cent. Dict. Paragenetic, of or pertaining to paragenesis [in biology or mineralogy]; originating by paragenesis; paragenic.

1951 W. H. Camp in Amer. Philos. Soc. Yearbk. 1950 166 (title) A biogeographic and paragenetic analysis of the American beech (Fagus).

1951 W. H. Camp in Amer. Philos. Soc. Yearbk. 1950 167 Thus by adequate paragenetic methods it has been demonstrated that certain of the beeches of this region have in them genic elements permitting them to be effective competitors in the forest community.

b. Genetics. Designating or relating to chromosomal changes or gene interactions that result in heritable alterations in the phenotypic expression of genes.

ΚΠ

1962 R. A. Brink in Q. Rev. Biol. 37 19 The point of view here developed leads to the suggestion that the chromosome characteristically serves what may be called a paragenetic, as well as a genetic, function. The former is primarily concerned with development of the individual, and the latter with heredity.

1993 Philos. Trans. (Royal Soc.) B. 339 174/2 Brink speculated that the mechanism behind paramutation would involve change not in the DNA, but in the organization of the chromatin encasing the affected genes. This led him to propose the concept of a paragenetic function for chromatin.

1999 Jrnl. Cancer Res. & Clin. Oncol. 125 123 This points to paragenetic elements that suppress suppressor genes and thus provoke melanoma at earlier ages of onset.
