Twin studies allow researchers to examine the overall role of genes in the development of a trait or disorder. Comparisons between monozygotic (MZ or identical) twins and dizygotic (DZ or fraternal) twins are conducted to evaluate the degree of genetic and environmental influence on a specific trait .

How do twin studies support the view that intelligence is inherited?
Genes have a very strong influence over how certain parts of our brains develop , scientists in the US and Finland have found. In identical twins, these areas showed a 95 to 100 per cent correlation between one twin and the other – they were essentially the same. ...
How does genetics and environment influence the similarities and differences within twins?
Any differences between identical twins is expected to be due to environmental factors since they are genetically identical , whereas fraternal twins only share half of their genes on average. ... When a genetic influence is dominant, the identical twins would have more trait similarity than fraternal twins.
Which personality has the highest correlation within identical twins?
The strongest correlation was found for neuroticism , yet with substantial associations also for extraversion and conscientiousness. In the multiple regression analysis including these three factors, only neuroticism and extraversion showed significant unique contributions.

What are the three types of genetic disorders?
