monogent

Monogent is a term used in speculative or informal discussions to describe a trait, system, or process that is governed by a single genetic factor or gene. It is not a standard term in formal genetics, where the concepts of monogenic traits and single-gene disorders are used instead. The word appears as a neologism combining the prefix mono- meaning one with gen(s) from gene, intended to emphasize a one-gene control mechanism rather than a complex, polygenic basis.

Usage and context: In fiction, thought experiments, or hypothetical discussions about genetics, monogent may be employed to illustrate how a single gene could determine a broad phenotype or a key biological function. In scientific discourse, however, the term is rarely used and may cause ambiguity; researchers typically reserve monogenic to describe inheritance patterns where a trait is determined by a single gene, sometimes with variable expressivity or penetrance.

Distinctions: Monogent is placed in contrast with polygenic or complex traits, which involve many genes and gene–environment interactions. The term aims to capture a one-gene influence more explicitly than broader phrases, but its lack of standard adoption limits its precision in scientific writing.

Limitations and reception: Critics note that monogent risks oversimplifying genetic architecture and may mislead readers about how phenotypes arise from genetic and environmental factors. When precision is needed, established terms such as monogenic trait or monogenic disorder are preferred.
