Document Summary
To what extent is the person we are shaped by genotype rather than environmental factors: the way we typically assess this is by comparing the phenotypic similarity of individuals whose genotypic similarity is, there are 3 kinds of design we use to assess the extent to which genotypic similarity contributes to phenotypic known. similarity, comparing the phenotypes of twins. If this is true, we would expect if we compare the similarity of monozygotic twin reared together in same family and compare that to similarity of monozygotic twin reared in separate family, we should see in both cases, the correlation between their iq is 1. 00. if this is true, it doesn"t matter if the monozygotic twin is reared in same family or different family: can also look at compared dizygotic twin reared together/apart and compare their correlation to monozygotic twin reared together/apart.
