Document Summary
Don"t copy slides refer to slide number. Read text to clarify conceptual information (even if it was not included in lectures) Proximate: the immediate sequence of physiological effects that lead to the behaviour . Ultimate: the adaptive value or evolutionary origins of the observed behaviour . Evidence for a genetic component to behaviour: deprivation experiments: Prevent learning opportunities through isolation of subject. Examples: squirrels burying, spiders web spinning, selection experiments: Step c) breed individuals with extreme phenotypes. Step d) measure phenotype in next generation. Step e) repeat breeding individuals with extreme phenotypes: crossing of genetic strains. Determining how breeding will affect the genetics: ex bees. When your do an f1 generation you get ur, ur, ur, and ur. Can be uurr, uurr, uurr, and uurr. After many generational crosses these traits are 1:1:1:1: molecular genetics. Mono amine oxidase (mao) mutations: neurotransmitter not broken down normally, hyper-aggressive disorder.
