Additive Genetic Effects for Schizotypy Support a Fully-Dimensional Model of Psychosis-Proneness

Schizotypy is an organization of traits mirroring psychosis-like symptoms and conveying individual psychosis-proneness. Schizotypy and schizophrenia share a genetic basis, wherefore initial schizotypy definitions considered a schizophrenic genotype as a condicio sine qua non. Since the search for a monogenetic schizotypy marker has proven in vain, it is believed that schizotypy is (genetically) based on multiple alleles, each of small...
