génelnyomás
Génelnyomás is a term that appears in some contexts related to genetics and heredity, though it is not a standard or widely recognized scientific term within mainstream genetics. It seems to be a portmanteau, possibly combining elements from "génétique" (French for genetics) and "pression" (French for pressure) or "dépression" (French for depression/lowering).

Alternatively, in less common usage, it could be related to concepts of genetic load or the reduction
