perinnollisen

Perinnöllinen is a Finnish term used to describe traits, characteristics, or diseases that are transmitted from parents to offspring through genetic inheritance. In scientific and medical contexts, it denotes anything arising from the genetic material that can be passed on generation to generation, as opposed to being acquired solely through environment or experience. The concept encompasses a range of inheritance patterns, from single-gene (monogeeninen) to polygenic and multifactorial inheritance, and includes both early-onset and late-onset conditions.

The form perinnollisen is the genitive singular of the adjective perinnöllinen. It is used to modify a noun in genitive case, for example in phrases such as perinnöllisen sairauden hoito (the treatment of a hereditary disease) or perinnöllisen taudin periytyminen (the inheritance of a hereditary condition). This grammatical form reflects Finnish sentence structure rather than a separate lexical meaning.

In medical genetics, perinnöllinen describes diseases or traits that arise from inherited genetic factors. Not all perinnöllinen conditions are present at birth; some may develop later in life or require environmental triggers to manifest. Perinnöllisiä tilojaಡ include mendelian single-gene disorders as well as complex traits influenced by multiple genes and environmental factors. The concept is closely tied to discussions of heredity, genetic risk, and family history.
