Fun in class.....

During my graduation, once, during our classes.... a guy in our class got a phone call. He asked permission from our teacher and hastily started going out... Before he could get out of the class, the teacher asked, "Is it XX or XY?" all of us were surprised and could not understand what the teacher was saying..... But, soon we burst out laughing immediately.

                          Actually, it was a genetics class, and according to genetics, the genes which differentiate between a male and female is the two sex chromosomes or allosomes. The female has XX chromosome and the male carries the XY chromosome. Our teacher was asking in that context whether the phone call was from a male or a female....? :))))) Interesting class it was and I just remembered it now and so, wanted to share with you people so that you can also smile at the teaching style of our teachers.....
