Document Summary
Behaviour genetics: study of individual differences in behavior that are attributable in part to differences in genetic makeup, genotype/phenotype, genotype is fixed at birth but is not static, phenotype changes over time, study of behavior genetic relies on 4 basic methods, comparison of members of family, comparison of twins, investigation of adoptees, linkage analysis, family method, average number of genes shared by two blood relatives is known. Starting point of sample: twin method, monozygotic (identical) and dizygotic (fraternal) twins are compared, concordance for disorder should be greater in mz than dz, mz are not always identical, equal environment assumption, environmental factors that are partial causes of concordance are equally influential for mz and dz pairs, equivalent number of stressful life experiences, adoptees method, molecular genetics, linkage analysis. Genetic differences reflected in temperament: temperament, constitutionally based differences in reactivity and self regulation, three types of categories, resilient type.
