Document Summary

3. 1 genetic and evolutionary perspectives on behaviour. Genetics has an influence on the brain. Genes basic units of heredity; genes are responsible for guiding the process of creating the proteins that make up our physical structure and regulate development and physiological processes throughout the lifespan. Dna a molecule formed in a double-helix shape that contains four nucleotides; adenine, cytosine, thymine and guanine. Genotype genetic makeup of an organism unique set of genes that comprise that individual"s genetic code. Phenotype physical traits or behavioural characteristics that show genetic variation, such as eye colour, shape and size of facial features and even personality. Chromosomes structures in the cellular nucleus that are lined with all of the genes an individual inherits. Homozygous two chromosomes are the same. Behavioural genomics the study of dna and the ways in which specific genes are related to behaviour (the human genome project) Behavioural genetics the study of how genes and the environment influence behaviour.
