Fill in what's been blanked out on the top pic. Obama, the tigers and the nasty female Culex are slightly indirect clues to the answer.

Answer's Teen Spirit - the deo and Cobain - the rest's common knowledge. Low hits on this one. Nikhil , ajay got it right (and Rishabh, over Google Talk). The clues were Obama- mulatto, white tiger - albino, Culex - mosquito. Self-explanatory, so I won't bother with the details.
