Document Summary
This is not true! (eg parents dress mz twins more similar than dz twins; mz twins have more friends in com mon than dz twins) so now the question is to what extent would the high similarities in environment of mz twins make us concerned about the he we obtain. evidence suggests that even though there are few environmental similarities that mzs have that dzs don"t, there"s nothing to prove that these small differences cause huge inflation to the mz hes we get www. notesolution. com. so it seems like a reasonable assumption to make even though it isn"t met all the time: representativeness: twins are like everyone else. There is nothing that distinguishes twins from non-twins other than the fact that they are born at the same time. This isn"t always true as well they are more likely to be born underweight, underage (prematurely) compared to non-twins.
