Introduction to Heredity

Today we started our discussion on heredity. This invovlved some videos that discuss identical twins. Why did I show that? Well.... First off a LOT of you were asking about the difference between identical twins, paternal twins, conjoined twins, etc. So these showed a LITTLE about these. Also though, I want you guys to see that there is a LOT that goes into the traits we have. While ultimatly our genes are what code for our traits the cellular environment also has dramatic effects on gene expression. We'll see how this blog goes and it will be a way to communicate with me!! Here we go :)
