alléltól

Alléltól is a Hungarian expression used in genetics to indicate that a trait, mutation, or genetic signal originates from a specific allele. It is formed from the root allél (allele) plus the postpositional suffix -tól, which marks origin or source. The construction appears primarily in formal or academic texts and is not common in everyday language.

Etymology and form: the term combines the genetic word allél with the suffix -tól, following Hungarian patterns for indicating direction or source. Alléltól reflects a focus on origin from an allele rather than a general statement about inheritance.

Usage and meaning: alléltól is used to attribute an observed characteristic to a particular allele, for example in pedigrees or studies describing allele-specific effects. It can appear in phrases such as alléltól eredő tulajdonság or alléltól származó mutáció. The phrase functions as a grammatical device to specify provenance and does not introduce a distinct biological concept beyond origin.

Relation to other terms: in everyday scientific Hungarian, az allélból (from the allele) is more common for indicating origin. Alléltól tends to appear in technical writing where the emphasis is explicitly on source or provenance of a genetic factor.
