Question

if ones identical twin (100% genetically the same) has schizophrenia, what are the chances that the other twin will develop the same condition?
○ a. 10 percent
○ b. 100 percent
○ c. 50 percent
○ d. 25 percent

Explanation:

In the field of Psychology (a subfield of Social Science), research on schizophrenia and identical twins shows that while genetics play a role, environmental factors also influence development. The empirical probability of an identical twin developing schizophrenia when the other has it is around 50 percent, not 100 (since environment matters), 10, or 25.

Answer:

c. 50 percent
