Document Summary
) by genes effects of history (via gene expression, neural pathways; learning) environment (social/cultural, biological) other genes is variation in behaviour genetic? between males and females? across cultures? biological underpinnings rats can learn from arbitrary cues and stimuli. Genetics of inbreeding deleterious alleles are rare carriers are heterozygotes risk of deleterious phenotype increased by inbreeding e. g. florida panthers. Inbreeding avoidance (non-human) many organisms: self incompatibility systems in plants big problems since they rely on pollinators like wind plants mate with themselves, but have developed genes to deal with it sex specific dispersal inbreeding aversion. Learning and cultural variation in non-humans different behaviours in different populations vocalization: cetaceans, songbirds whales and songbirds learn songs from each other. chimps: there"s variations in styles of particular behaviors termite fishing learned by daughters (different types of termite fishing according to the population they"re in)
