Quizplus · Accepted Answer

Fraternal twins share about half their genes with each other, just like any siblings. Therefore, their IQ scores are expected to become more different as they grow older and have different life experiences. However, at around 15 years old, their IQ scores are likely to be most similar, as they would have grown up in the same environment and would have had similar experiences up until that point.
