| Summary |
What's it like to grow up with another you? To share, not only your face - but maybe also your thoughts, your dreams and even your pain? That's a question only identical twins can answer. This week on Insight, a group of twins, 22 identical pairs, get together to let us in on the secret. Some twins say they are like two halves of one self; others that they have quite different personalities. It's those similarities and differences that fascinate scientists. Studies of identical twins, with their identical DNA, have led to some startling findings about nature and nurture. Growing up, twins share both their genes and their environment. They are a perfect genetic design for studying what makes us the way we are. Twin studies reveal that our behaviour, our health and most things about us, have a lot more to do with our genes than we used to believe. Even our personality is around 50% inherited. Professor Nick Martin, a leading geneticist from Queensland, has studied twins for nearly 30 years. 'Everything about us has a genetic component ', he says. Even things like our social attitudes, how much you watch TV, how successful your marriage is - are all genetically influenced, although some much more than others |
