Of course Helel, but there is still the possibility of some traits being statistically more represented in one or the other gender. One of the most obvious examples are violent aggression which tends to be more prevalent in males. Something similar might be found in regards to curiousity, though I am at a lose of how to investigate it. But if you are to hazard a guess it is prudent to focus on the ways gender roles encourage curiousity or not as, at least unless you believe that there is something essential in the differences between genders.
Still it is mostly a meaningless question as there are too many elements of curiousity and too many options of being curious about something and not about something else, to say something specific. For example I have next to no curiousity about recent trends in car modification, but if Discovery Channel is to be trusted there is a huge demand for information about this. So any answer will depend on what knowledge we focus on and given the lack of statistical information ultimately our own judgement based on anecdotic evidence, personal beliefs, what we feel like when answering and probably several other factors and not any real knowledge.
