Document Summary

How is more complex behaviour coded? (p. 111-119 next class) Ask question not in ask mike chapter for online discussion and answer someone else question. Nature something we are born with v. s. Came to conclusion that there is a healthy balance of both to form a human. The in uence of genes is through protein synthesis there are no genes for a particular attribute. Reaction time poses as an experiment to somewhat determine intelligence because neurons are better connected. Environment can in uence protein synthesis as well. Ex. what you eat can determine the production of protein molecules. Genes determine range of possibilities, but not degree of expression. Environmental exposure at speci c interval is critical. E. g. white-crowned sparrow must hear adult song between 7th and 60th day. Phenotype: outward expression of genotype (characteristics, behaviours, etc. ) **outward characteristics may not indicate underlying genetic contribution** ex. hair colour may be genetic, but can also be altered in other ways.
