Modern genetics and behaviour
Most modern genetics research seeks, not to 'improve' the human race, but to advance the health and choice of the individual. Understanding human behaviour may help develop new ways of treating addiction, anxiety and eating disorders. Each of us has about 24,000 different genes, of which 30,000 are used in our brain cells. Scientists are only beginning to find out what all these genes do, how they work together, and how they interact with our environment.
