polygenisk
Polygenisk is a term used in genetics and evolutionary biology to describe traits or conditions influenced by multiple genes rather than a single gene. Unlike monogenic disorders, which are caused by mutations in one specific gene, polygenic traits arise from the combined effects of several genes, often interacting with environmental factors. These traits typically exhibit a range of expressions, known as continuous variation, rather than distinct categories.
Examples of polygenic traits include human height, skin color, and susceptibility to complex diseases like diabetes,
The study of polygenic traits relies on statistical methods, such as genome-wide association studies (GWAS), to
Polygenic inheritance is also relevant in selective breeding and agriculture, where breeders aim to enhance desirable
