Genetics: The study of genes and how they are inherited. In the context of schizophrenic spectrum disorders, genetics helps us understand how certain genes may contribute to an individual's susceptibility to develop these disorders.
Heritability: 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.
