Today's Daily Question was based off of this concept map
After going over this - we then started to take an inventory of our traits - always a favorite!! Some of the traits we looked at: Widows peak, tongue rolling, cleft chin, Dimples, and whether you can taste PTC (phenylthiocarbamide) or not. After looking into this more - APPARENTLY this is a myth that it is only one gene that determines if you can taste it or not. For more information you can go to http://udel.edu/~mcdonald/mythptc.html Basically what this is saying if that environmental factors play a role as well. This is not a suprise at all, as we will see later in this chapter that MOST genes are influenced by the cellular environment and there are hardly ANY characteristics that we have that follow simple mendelian patterns of heredity!!
