Evaluation

• :) Real world applications e.g. drug therapies such as SSRIs for the treatment of psychological disorders such as depression and OCD
• :) Another practical application

  Family history is a reliable predictor of an individuals disease risk due to an understanding of genotype combined with enviromental factors
• :) Evidence to support the influence of genetics on behaviour and traits

  Many large-scale twin studies that have shown high concordance rates e.g. study done on IQ

  MZ twins showed a correlation of +0.9 (massively significant)

  Shows that genetics influence characteristics
• :( Arguing that complex human behaviour is a product of genetics alone is an example of biological determinism

  This is a reductionist view which ignores the effect of environmental factors on behaviour

  Saying that genetics play a huge influence on behaviour is implies that humans lack free will to go against our own genetics
