As a Gemini family you are part of a landmark study of growth from birth to 5 years involving 2400 families from all over England and Wales with twins born in 2007.

It is the biggest study of the genetic and environmental effects on appetite and growth ever to be undertaken.

The aim is to find out how basic biology and the world around us work together to make us who we are.
