Debate are you born with it or is it part of your environment? . More so how do nature and nurture interact with eachother in order to influence someone"s behaviour. Can"t separate them from one another: impossible to separate genetic influences from environmental influences, they can work together to determine human behaviour. Epigenetics changes in gene expression that are due to non-genetic ( epi" outer") influences (environmental influences) Heredity the genetic transmission of characteristics from parents to offspring. E. g. , ada might say that she inherited her blue eyes from her dad. Heritability an estimate of the genetic proportion of the variation in some specific trait. In a particular population, this trait varies heritability is 0 if there is no variation. Estimate of heritability % of the variation that is explained by genetic differences.
