I'm not sure I fully understand the question, but a simple way to 
represent genes for an agent is using a list of values.  When an agent 
inherits the behaviors from a parent, you can do a "copylist" to copy 
the parent behaviors and then use mutation or crossover on the 
resulting list or lists.  You then use the values in the list to 
represent the various qualities of the agent.

If you really want to mix and match different subroutines, then you 
might want to look at the support for the Push language that is 
provided with breve.  Push is a genetic programming language that 
allows you to evolve full programs which can run subroutines in breve 
code.  Look at the SwarmEvolve2 demo for an example of how Push is used 
to evolve control programs for evolving agents.
