The only pair that were mentioned as being twins are Greg and Craig, who are identical twins. Identical twins share the same genetic material and therefore tend to have very similar IQ scores. Biological siblings (A and B) and fraternal twins (C) do not necessarily share the same genetic material to the same degree, and their IQ scores are therefore more likely to differ.
