I believe that process oriented classification schemes represent the best
Let's consider the analogy between computer files and genes. Both are made
up of code, but neither is dependent on spatial organization. Both
computer files and genes 'work' regardless of where they fit in the 'memory
space.' We call a file a 'copy' if it performs in the same manner as the
original. The same is true for genes.
If it is true for computer files and genes, the scheme ought to work for
