Document Summary

Every human: 23 chromosomes (each pair has one element contributed by mother, one by father) In each pair there is a gene on strand of dna (double helical strand) Gene codes for aspect/characteristic of us (eye colour) Alleles: gene versions, result that is expressed = trait. Single-gene trait: one gene determines, i. e how anxious you are. Polygenic trait: multiple genes, i. e iq comprised of multiple things. Behavioral genomics: francis galton, 1869. i. e studying gene that codes for creativity. Argued that genius is heritable (some factors have nothing to do with genes but instead with environment person is exposed to, such as access to supplies that influence creative behavior i. e access to art supplies, social network) Concordance rate: % of time they both share same outcome. Look at twins that have been separated at birth, analyze concordance rate to see if environment has influenced behavior. Evolutionary psychology and functionalism: how did behaviors contribute to evolution.
