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).

The exact meaning can vary depending on the source, but it generally refers to a hypothetical pressure or force exerted by genes that influences biological traits or developmental processes. In some discussions, it might be used metaphorically to describe the cumulative effect of multiple genes on a particular characteristic, implying a strong genetic predisposition.

Alternatively, in less common usage, it could be related to concepts of genetic load or the reduction of genetic diversity within a population, akin to a "depressing" effect on the gene pool. It is important to note that the concept lacks a rigorous scientific definition and is not typically found in peer-reviewed genetic literature. Researchers in genetics usually employ more precise terminology to describe genetic influence, such as polygenic inheritance, gene expression, or allele frequencies. If encountered, it is advisable to seek clarification from the specific context in which the term is used to understand the intended meaning.
