Document Summary
The inheritance of personality: behavioural genetics and evolutionary theory. Inherit wealth: child"s parents already rich, so children inherit all. Inheritance o advantages/disadvantages of wealth (ie. rockefeller family). Behavioural genetics: individual differences in behaviour (personality traits) passed on by biological relatives. (personality attributes inherited, both ancient and recent ancestors) Evolutionary psychology: patterns of behaviour (characterizing all humans) b/c survival value over the history of species (across generations) Family resemblance (physical appearance): how you all look shared because of genes shared. Family resemblance (personality): are you psychologically similar (traits) to your biological relatives: personality traits: a pattern of behaviour relevant to more than one situation ( trait genetics but behavioural genetics is the traditional term) Neither are feasible, unlikely to breed ppl to specification or duplicate ppl because personality is result of complex interactions of genes and environment. Measure who are/aren"t genetically related, or related to different degrees. Phenotype: the observable traits of a person.
