ALLOGENIC

Etymology

Adjective

allogenic (comparative more allogenic, superlative most allogenic)

Having an external cause, or source; exogenous.

(geology) Formed in another location and transported.

(medicine, biology, genetics, immunology) Alternative form of allogeneic: genetically distinct, but of the same species; nonself but intraspecies.

Usage notes

Do not confuse allogenic ("of nonself intraspecies origin") with allergenic ("generating allergy"); the two concepts are often related (because allergic reactions can potentially be caused by any antigen and usually/especially by nonself antigens), but the similar sound of the two words is due only to partial cognation of the word roots.
