Can you explain this a bit more?
- barry-cotter 7y agohttps://en.wikipedia.org/wiki/Twin_study https://en.wikipedia.org/wiki/Twin_study > The classical twin design compares the similarity of monozygotic (identical) and dizygotic (fraternal) twins. If identical twins are considerably more similar than fraternal twins (which is found for most traits), this implicates that genes play an important role in these traits. By comparing many hundreds of families with twins, researchers can then understand more about the roles of genetic effects, shared environment, and unique environment in shaping behavior.
