PETS is a study of twins, from when they were in the womb through to childhood and beyond. The study aims to identify what makes us all who we are; our health, development and well being. Where better to start than with twins, who share the same mother, but are usually in their own ‘sac’ during pregnancy, then share the same home environment as children. Despite this, even ‘identical’ twins can have different personalities, physical characteristics and illnesses. Why is this?
