While twin studies offer valuable insights, they have limitations:
- Generalizability: Findings from twin studies may not always be applicable to the general population, as twins represent a specific subset. - Shared Environment: Monozygotic twins often share the same upbringing and environment, making it challenging to completely separate environmental influences. - Epigenetics: Differences in epigenetic modifications can also contribute to variations, complicating the analysis of purely genetic versus environmental effects.
