On one hand, in spite of our developmental and functional complexity, the number of genetic rules is surprisingly small. The mechanisms of inheritance are generally so direct that most examples are "typical." But that is not always the case. The path from an inherited DNA sequence to an expressed phenotype can sometimes be a convoluted and complex one. Most of the time this complexity is seen in the way genetic processes and their products interact with each other and with the environment. But not always.
