Subject: Displaying object variables, not obj ID

I'm having problems with displaying an object correctly. I keep getting the
obj's ID back, like this:

sendto("Chromosomes:   " + p.c_chromosomes.to_s)     #  sort of 'puts' =3D>
Chromosomes:   #<Chromosome:0x10267658>

Checking with the Pickaxe, I see they have a solution (no obvious
explanation though), where they suggest redifining to_s to accomodate its
purpose in their 'song' class. This is no good for me though, as to_s will
be used to display a lot of things, not just chromosomes.

Uhm. I feel like I should provide more info to ensure an accurate answer,
but I'm not sure what or how much is necessary.
Perhaps that the variable actually saves right in the yaml file:

...
c_chromosomes: !ruby/object:Chromosome
    c_chromosomes:  # hash of arrays
      symmetry: []
...

Any insights would be much appreciated.
Tobias
