Document Summary
O 2) family studies: 3) twin studies, 4) Three pigs with green fluorescent protein (gene taken from jellyfish) To see if it"s possible to manipulate people"s dna at some point, might be able to correct/fix genetic disorders. But we can"t do this selective breeding for people. For people, take advantage of what we already know about natural process: gene transmission based on characteristics of how family is organised . We"re starting to shift into the specifics about what we do in personality research. More physiological-based ways of assessing behaviour, etc. Twins raised apart are incredibly tough to find, but very valuable. Can measure trait of dominance for twins: correlation for mz= 0. 57, correlation for dz= 0. 12, formula: h=0. 90 (2 * (diff. ), but this is an overestimation, point is that this trait is strongly heritable. Neuroticism: mz- 0. 93, dz- 0. 48, h- 0. 90, mz- 0. 51, dz- 0. 18, h- 0. 66, mz- 0. 46, dz- 0. 20, h- 0. 52.
