This picture book is designed to accompany the booklet: "Information for parents who are considering whether to talk about an extra Y chromosome with their son and family members". It provides a simple explanation of how an extra chromosome can affect a child's development, but does not attempt to explain genetic mechanisms.

If you would like a hard copy of either or both of these booklets, please contact Sarah Wynn at the email address above.

This work would not have been possible without the generous support of the Nuffield Foundation, and Unique. The research supporting this booklet was conducted at the University of Oxford and directed by Professor Dorothy Bishop and Professor Gaia Scerif.
