inherited
twin studies - concordance rates are calculated. (extent to which twins share the same characteristics) =
GENETIC
inherited
twin studies - concordance rates are calculated. (extent to which twins share the same characteristics) = higher concordance = mz twins (100%) / lower in dz twins (50%)
GENOTYPE
genetic make up
PHENOTYPE
combination of genetics and environment
GENOTYPE AND PHENOTYPE
suggests that human behaviour depends on the interaction of nature and nurture
DARWIN - NATURAL SELECTION
any genetically determined beh. enhances survival and reproduction - future generations
DARWIN
Genes are adaptive and give offspring advantages
DARWIN
attachment beh. in newborns promote survival = adaptive and naturall selective
