Heritability refers to the extent to which genetic factors contribute to a trait or disorder. When studying schizophrenic spectrum disorders, researchers look at heritability to determine the role genetics play in their development.
Polygenic Risk Score: A polygenic risk score is a numerical value that estimates an individual's genetic predisposition for developing a specific condition or disorder. Scientists use polygenic risk scores to assess the genetic contribution to schizophrenic spectrum disorders in individuals.
