WebApr 28, 2015 · If the EEA is violated then the ACE model – which assumes clear separation of variance A from variances C and E – becomes infeasible. During the first 45 years of the twin method (roughly 1924–1969), the assumption that identical and fraternal pairs experience roughly equal environments became infeasible (22, 25).
