Influence of Genes

• Genes are passed down from one generation to the other
• Genes carry the instruction for a particular characteristic ( temperament / intelligence )

  BUT how this characteristic develops depends on how genes interact with other genes and the environment

  Generates the nature - nurture debate
• Genotype


  Our genetic code

  Actual genes
• Phenotype 


  How our genetic code is expressed in our appearance / behaviour
• Genetic mutation occurring in the population

  Means natural selection can apply in psychology
