Researchers agree that schizophrenia is about 80% heritable.

Explanation:

This mental illness can be hereditary in most family when there is a diangises. However, it does not have to be a close family member such as a mother, brother, sister, or father. This mental illness can be passed down generations and skipped generations. Uncles, cousins, and a grandparent from  the past may have suffered from schizophrenia. In addition, Autism is another illness that can be hereditary.

This mental illness is not based on genetics alone, and each family will be spoken to by a medical professor to see where the mental illness originated. There are still 20% of people with schizophrenia that have no family that has the mental illness.
