he is experiencing dissociative symptoms of schizophrenia.
he is experiencing negative symptoms of schizophrenia.

Explanation:

• For John's case: Dissociative identity disorder (DID) involves having two or more distinct identities or personality states. John has two states - his usual self and Andrea, which fits DID. Major depressive disorder is about persistent low mood. Schizophrenia has symptoms like hallucinations/delusions (not shown here). Gender dysphoria is distress from gender incongruence (not indicated here).
• For Tyrone's case: Positive symptoms of schizophrenia include hallucinations (seeing cats that aren't there) and delusions (believing he's a dog). Epigenetic is about gene - environment interaction (not a symptom type). Dissociative symptoms are more about identity disruption (not here). Negative symptoms are like lack of emotion/motivation (not shown).

Answer:

• John: John might suffer from dissociative identity disorder.
• Tyrone: He is experiencing positive symptoms of schizophrenia.
