And the only word that came to mind was "COOL". Was very busy during the past month on my job so it was a great refresher coming back and brushing up my combinations and probability :)....am really looking forward to more of your math posts that have once again sparked my interest in math after my university professors had managed to kill it. In the meanwhile I will be treating myself to some of your other posts which I have missed over the course of the past month. Your fan from Pakistan I came to your website after a while Kalid.

I had completely forgotten about mixing genes in biology, but that's exactly it. The child gets (x OR x) AND (x or y) = (x + x)*(x+y) = 2xx + 2xy, or an equal chance as you say. @sgwong: Glad you liked it -- I use PowerPoint 2007 to make the diagrams. @Presh: That’s a great use of this trick!
