Can I assign fields a name that is different to the question text/title?

I would like to ask a Single Choice Question such as 'What is your gender?' and allow the choices of 'Male, Female or Other' and post the answer to my PHP script which I can do easily. However, I would like this answer to be from the list of 'M, F or O'. In other words I would like to return an answer that is different to the displayed options.  Is this possible somehow ? Thanks.

Then you can collect the result in a Form Calculation widget:
