Document Summary
Gene that codes blood type is a polymorphism with its alleles being a, b, and. O: polygenic = a trait or characteristic that is under the influence of multiple genes. Familial transmission of crime: could indicate the transmission of genetic influences from one generation to the next, could also be a sign of social transmission resulting from circumstances such as poverty etc. Adoption studies: help to separate the effects of genetics and the environment. Nature vs. nurture: other genetics and environment are influential, environmental effects are the stronger force, offending is seen as the result of nature + nurture. Models of gene-environment interactions: diathesis-stress model, differential susceptibility model. Differential susceptibility model: puts together the biological sensitivity to context theory + the differential susceptibility theory. Individuals exhibit gene-based differences in their sensitivity or reactivity to the environment: people are environmentally sensitive to both adverse and favourable conditions.
