Is girl stronger then boy in chess ?

Is girl stronger then boy in chess? I asked this question because last night in Group C, Corus Tournament, the 2008 World Junior Champion (Boy) - GM Abhijeet Gupta lost to the 2008 World Junior Champion (Girl )- WGM Dronavalli Harika ! Interestingly both are from India and one more fact, Dronavalli (photo right) won the game as black ! Below are the game.

I bet Haslindah Ruslan and Susan Polgar must have been happy win this game !

GM Abhijeet Gupta ( 2569) - WGM Dronavalli Harika (2473) [D10]
Corus C , (Round 1), 18.01.2009

Probably Abhijeet (photo left) lost on time.
