 Set point model of personality stability and change | A model that attempts to explain the stability and change in adult personality. Genes end up influencing a "comfort range" or a "set point." Much of the stability in adult personality is due to genes |
| Meritocracy | One's own social status depends on their merit |
| Heritability | The extent to which phenotypic variance is predictable from genetic variance. Denoted as an (h2) |
| Environmentability | The extent to which phenotypic variance is predictable from environmental variance. Denoted as an (e2) |
| endophenotype | Physiological or biochemical phenotype that is closer to gene action than the phenotype you are studying. Before signs and symptoms of the studied disorder develop (Genes controlling abnormal eye tracking linked schizophrenia) |
| Naturalistic fallacy | Attributing some type of moral correctness for a phenotype developed through evolution, and this myth is often misused in genetics and human behavior |
| Smorgasbord model of personality development | Genes are taste buds, environments are different dishes. End result is that we self-select environments based upon our genetic dispositions |

| Heritocracy | Social status (education, income, occupation) depends on family |
| 5 forces of human evolution | natural selection, mutation, genetic drift, population structure, cultural evolution |
| natural selection | adaption to environment, heritable traits |
| mutation | Differential DNA copying variations in either somatic or germinal cells that are transferred to the next generation; the only mechanism for new genetic variation into population |
| genetic drift | Changes in gene or allele frequencies by chance alone. Biggest influencing factor is population. Smallest populations most affected |
| Population Structure | nfluences who mates with whom in a species |
