Document Summary

Genotypes: gene combinations, expressed through phenotypes (e. g, gene for green eyes) Phenotype: the manifestation of complex human traits (e. g. , a person having green eyes) Phenotype = genotype + environment + genotype-environment correlation + genotype- environment interaction. Behavioural genetics: the study of genetic and environmental contributions to individual differences in personality and behaviour. Human behaviour (and personality) is a combination of both genes and genetics. Nature and nurture work together to produce personality and human behaviour: genotype-environment correlation: explains how we can"t separate the impact of our genes on the environment; occurs when a genotype is exposed differently to an environment. People modify, create, and re-create in our memory our experiences. Passive genotype-environment correlation: when parents provide both the genes and an environment that is favourable or unfavourable to the development of those genes. Reactive genotype-environment correlation: when parents respond to something in their child: active genotype-environment correlation: when children seek out the more responsive parent or grandparent.
