Document Summary
3. 1a psych: genetic and evolutionary perspectives on behaviour. Behaviour genetics- individual differences, due to genetic differences, mutations not affected by natural selection. Evolutionary psych- universal commonalities, due to genetic similarities, mutations that conferred a reproductive advantage to all. Behaviours are influenced by genes just as physical characteristics are. Genes- the basic units of hereditary; genes are responsible for guiding the process of creating the proteins that make up our physical structures and regulate development and physiological processes throughout the lifespan. Genes are comprised of segments of dna. Dna (deoxy-ribonucleic acid)- a molecule formed in a double-helix shape that contains. Genotype- the genetic make up of an organism: the unique set of genes that comprise that individual"s specific code. Unique code formed of nucleotides to make proteins. Phenotype- physical traits or behavioural characteristics that sho genetic variation, such as eye colour, shape and size of facial features, and even personality.
