different since they have different genes. This principle is supported by Bouchard’s correlational twin study. The study observed two types of twins‚ monozygotic twins reared-apart (MZA) and monozygotic twins reared together (MZT)‚ in order to determine the influences of genes and environments on behavior. As the word monozygotic implies‚ they used identical twins; in other words‚ each twin shared same genome. Bouchard then preceded lots of psychodynamic tests and compared the differences between

also looked at schizophrenics whose father had an identical twin. He found that there was a 17% of being schizophrenic when the father was but he also found that there was also 17% chance of developing the disease when the father’s twin had schizophrenia but the father didn’t. MZ twins share 100% of their genes; DZ twins share 50% of their genes. If genes are a factor we would expect more identical twins to share the disorder than non-identical. Rosenthal took a case study which had a set of female

History of the Nature- Nurture Debate Intellectual thinking in the 17th Century was

Studies have used large samples of identical and fraternal twins to disentangle the role of genes and environment in entrepreneurship. Identical twins share all of their genes while fraternal twins share‚ on average‚ half of their segregating genes. As a result‚ greater twin concordances – the probability that a twin is an entrepreneur given that its co-twin is also an entrepreneur – for entrepreneurship between pairs of identical than between pairs of fraternal twins can only be
