How is mental illness checked and will it be inherited?

Patient's question:

Schizophrenia since 2005, triggered by the death of parents

Doctor's answer:

If the father has schizophrenia, the probability of his children developing schizophrenia is slightly higher than that of the general population.
Advice: Schizophrenia also has a certain genetic component, but his children are not 100% guaranteed to develop schizophrenia. Schizophrenia is not a genetic disease; it is only associated with genetics. There are many other factors related to the onset of schizophrenia.
