Document Summary
Complete set of genes an organism possesses. Human genome project: number of genes is similar to other species but genes are decoded more variably, what were thought to be genetic junk potentially impacts everything from physical size to personality. Some genes that differ across individuals influence the behavioural characteristics. Design the future of the human species by fostering the reproduction of persons with certain traits and by discouraging the reproduction of persons without those traits. Knowledge is better than ignorance; doesn"t have to be used for evil. Behavioural geneticists are not content with figuring out the percentage of variance. The proportion of observed variance in a group of individuals that can be accounted for by genetic variance. Environmentality: percentage of variance attributed environmental differences. The larger the heritability, the smaller the environmentality and vice versa. Can be applied to a single individual (it can"t) Genes and environment are inextricably intertwined, cannot be separated.
