Psychology chapter 4 - nature, nurture & human diversity. Behaviour genetics: the study of our differences & weighing the relative effects of heredity & environment: people have been thinking about nature vs. nurture for a long time. Chromosomes: structures made of dna that contain genes (we have 46: situated in the nucleus of the cell. Dna: contains genetic info that makes up chromosomes: humans share nearly all of their dna with one another. Genome: the complete instructions for making an organism, containing all the genes in that organism: the gene pool of a complete species. Twin adoption studies: studies the effect of heredity & environment on twins: identical twins separated at birth provide most data about nature vs nurture. Monozygotic twins: genetically identical twins that developed from one egg: allows us to study nature vs nurture without any other variables, 1 in every 3 sets of twins have separate placentas = different nourishment.
