Document Summary
Module 3. 1- genetic and evolutionary perspectives on behaviour. ~humans tend to think, black vs white, true/false, yes/no. ~as a matter of fact, both influence us, they are not mutually exclusive. Genes are found in the nucleus of most of the billions of cells in the human body. Genes: the basic units of heredity; genes are responsible for guiding the process of creating the proteins than make up our physical structures and regulate development and physiological processes throughout the lifespan. Dna (deoxyribonucleic acid): a molecule formed in a double-helix shape than contains four nucleotides: adenine, cytosine, guanine, and thymine (a,c/t,g) Genotype: the genetic makeup of an organism-the unique set of genes that comprise that individual"s genetic code. Phenotype: the physical traits or behavioural characteristics that show genetic variation, such as eye colour, the shape and size of facial features, and even personality. Chromosomes: structures in the cellular nucleus that are lined with all of the genes and individual inherits.
