Looking in the Mirror at Two Genes

The Prelude Have you ever stood in front of a mirror, I mean really stood in front of a mirror and just wondered what were you going to look, or act like, when you got older? You might have even asked yourself questions like; am I going to be skinny, or fat, will I be tall or short, how will I look with a full head of hair, or just plan bald, will I have big breasts or no breasts at all? And just maybe, as you were looking into this reflecting glass of many mysteries, you realized that the answers to your questions were too obscure to see.
