D002. IQ scores of 32 paris of twins
The data file can be downloaded here:
This dataset contains the IQ scores (iq
) of identical (monozygotic) twins (twin
) that were separated early in life and reared apart. Univitelline twins are very important for genetic studies because they share virtually identical genotype. The data corresponds to a total of 32 pairs (pair
) of twins where one of the members (twin = A
) was reared by their natural parent, and the other (twin = B
) was reared by a relative or other person (McClave and Sincich 2009).
