PSYB30H3 Chapter Notes - Chapter 6: Selective Breeding, Heritability, Eugenics
Document Summary
Genome: the complete set of genes an organism possess; the human genome contains somewhere between 20,000 and 30,000 genes (1) manner in which human genes decoded into proteins more variable than other species (2) Junk dna 98% - potentially affecting physical + personality. Eugenics is the notion that we can 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. Percentage of variance: refers to the fact that individuals vary, or are different from each other, and this variability can be partitioned into %"s that are due to different causes. Heritability: is a statistic that refers to the proportion of observed variance in a group of individuals that can be accounted for by genetic variance. Environmentality: the percentage of observed variance in a group of individuals that can be attributed to environmental (nongenetic) differences.
