D) they have very different gray-matter volume.

Question

Quizplus · Accepted Answer

Identical twins share the same genetics and prenatal environment, which leads to them having very similar gray-matter volume. Therefore, the MRI findings will most likely indicate that they have very similar gray-matter volume. Options A and B are unlikely, as intelligence is not solely located in one specific area of the brain, and there is no evidence to suggest that the twins would differ significantly in this regard. Option D is also unlikely, as identical twins tend to have very similar brain structures.
