3. 1 genetic and evolutionary perspectives on behaviour. Behaviours are influenced by genes just as physical characteristics are; the two are related. Genetics has an influence on the brain. The work of genes both during development and during everyday life has a dramatic effect on your behaviour. Genetics is found in the nucleus of most of the billions of cells in the human body. This genetic material is organized into genes. Genes: the basic units of heredity; 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 composed of segments of dna (deoxyribonucleic acid) Dna: a molecule formed in a double-helix shape that contains four molecules: adenine, cytosine, guanine, and thymine. Genotypes: the genetic makeup of an organism the unique set of genes that comprise that individual"s genetic code.
