Landon and Logan are identical twins who have been raised in the same family and attended the same schools. As a result, their environments have been very similar. Landon is goal-oriented and driven while Logan is laid back and easy going. How would researchers explain this personality difference?
◦ Since genetics should explain all personality differences, there must have been a genetic mutation.
◦ Shared environment is less important than once thought.
◦ Only 40 percent of personality is inherited.
◦ There is no way to explain their differences.
