is it possible too change a pokemon's type depending on the gender?

I'm currently editing pokemon white and want to change unfezant F type to flying/ground without changing unfezant M type is this even possible?

It depends on whether the personalinfo of Gen 5 stores Unfezant female as a different form.

I'm new to rom hacking, how would I be able to find out?

check the personalinfo file. I'm not going list out the steps to get to it and how to check.
