Biological

• Assumptions:

  Behaviour is influenced by the central nervous system, genes and neurochemistry

  Behaviour is a product of evolution
• Genes - a unit of inheritance; they consist of DNA which tell your body what proteins to manufacture.
• Genes are inherited from parents and contribute to the development of an individuals characteristic.
• Neuroanatomy - the study of the structure and organisation of the nervous system.
• Neurochemistry - the study of chemicals and their reactions in the nervous system.
• Nature - the influence of biological processes on behaviour, including genetics and hormones.
• Nurture - the influence of the environment on behaviour and development.
• Genotype - the genetic makeup of an organism; It consists of all the genetic information that determines the characteristic of organisms
• Phenotype - an individual's observable traits ( height, eye colour, blood type and the presence or absence, after an interaction with the environment). The genotype and environment contribute to the phenotype.
