When asking the question about gender we need to take into account the person's identifying gender but still need to know their biological gender. I would like to understand the best combination of questions to ask this.

The current system is just "Male" / "Female" and we don't the people who just use that have extra to click.

I was thinking of changing this first to "biological gender" and adding a third option to allow the user to show that their identifying gender is different.

Or alternatively a second question is "This your identifying gender" but then everybody would have to answer it.

What is an ideal sequence of question and answers to determine both biological gender and identifying gender?

Also considering mobile vs desktop.

    In many cases, gender really doesn't need to be known. Do you have a legitimate reason to ask that question? Commented Aug 30, 2017 at 20:43

    Gender and Sex are different things. 'Biological Gender' is not really a meaningful term. en.wikipedia.org/wiki/Sex_and_gender_distinction

Since the biological sex and the identifying gender will be the same in most cases, you should avoid forcing users to explicitly select both.

You could let all the users select their biological sex, and let them specify a different identifying gender only if they click on a link that says something like "My identifying gender is different". Most people won't need to be prompted with a second gender select form, and they won't mind not having to click on that link.

Keep in mind that this is a really sensitive data; so you should comply with many strict privacy regulations.
