Does bonus feats qualifies for Prestige Classes?

[darwin.evenwood]

Hello, i would like to ask if bonus feats given from items or weapons (such as "weapon focus: kukri") qualifies for prestige classes and improved version of the feat itself.

I mean, for example, i am playing a kukri wielder who wants to go dervish later. I've got a kukri with focus and specialization as bonus feats, does they work to qualify for the class? Will i be able to pick greater spec or even epic spec later or should i pick previous feats at levelling? what if i unequip the kukri whose giving me bonus feats?
I know they are a lot of question but i would really like to know this! thanks a lot and have fun!

Hello there. Bonus feats from items dont qualify for prestige classes and improved version of the feats.

Thanks a lot for your quick answer!
I will plan my build in a different way then.
