Document Summary

People are also afraid that police systems will be driven to base a lot of their information on genetics. Therefore, political agendas might be driven by these findings: eugenetics: the controversy regarding using eugenetics to knockout specific traits. Percent of variance: there are differences between people due to a certain cause (in percentages). Many times this is used to look at what percentage of a personality trait is a product of genetics or the environment. These percentages are not concrete however, there might be errors or differences between different studies. Heritability: amount of phenotypic variance in a group due to genotypic variance. Environmentality: amount of observed variance due to the environment. If personality traits are heritable, you should see personality traits across generations of a family. In family studies, you examine correlations between genetic relatedness of family members and personality similarity. Within families, there is a percent of shared genes.
