What makes twin research a valuable source for observation? Provide an example.
Twins are valuable for observation because 'identical' or monozygotic (MZ) twins share essentially 100% of their genes, which allows the study of environmental influence and varying genetic makeup. An example of this is tracking traits ranging from personal behavior to severe mental illnesses such as schizophrenia.
Discuss the broader methodology used in behavior genetics and how twin studies fit into it.
