Quizplus · Accepted Answer

Tabia is most likely to be diagnosed with schizophrenia because having an identical twin with the condition significantly increases one's risk due to sharing the exact same genetic makeup. Identical twins have a much higher concordance rate for schizophrenia compared to any other family relationship.
