Under equal opportunities you often don't have to declare things like your age, gender, religion etc. However, most of the time giving your name gives away your gender but in some instances it may not.
For example:
Alex is used as a shortened form of both Alexander and Alexandra.
Ali is increasingly being used as a shortened form of Alison as well as being a male name of Arabic? origin.
Charlie is increasingly being used as a shortened form of Charlotte as well as Charlie.
Jo is normally a shortened form of Joanne/Joanna with Joe being a shortened form of Joseph but there's exceptions e.g. Jo Johnson and Swedish novelist Jo Nesbo.
Sam is used as a shortened form of Samantha and Samuel.
Are there many other names from which you can't tell the gender of the person from the name?
