A genetics survey has been set up online to find out how many people want to know what medical conditions they may face in the future.
The survey is being conducted by the Sanger Institute in Cambridge, which played a big part in mapping the human genetic code.
By examining DNA, doctors can tell if people are likely to develop medical conditions like diabetes, Alzheimer's and cancer. The institute is trying to establish whether or not people would want to know.
