The structure of the "web" (graph) of mates and offspring will be very interesting ...

For example, let's say that I have a creature of type X (e.g., Spider Occultist) with very high (+1000) Gene Strength that I have worked very hard to create. If I want to change up my team, it is natural to ask the question:

"Is there a [relatively short] sequence of mates that I can breed (successively) with my type X creature in order to produce a creature of type Y? (That is, can I do a sequence of breeding steps that I can do to transfer my very high Gene Strength to a creature of a different type?)"

It will be interesting to see for what percentage of pairs (X,Y) can you get from X to Y in less than (say) 6 breeding steps. (I.e., six-degrees of separation <grin>) ... And for what percentage of pairs (X,Y) it is possible to get from X to Y in a finite number of breeding steps.

Also related to the connectivity of the breeding web/graph ... It will be interesting to see whether there is a "Kevin Bacon" (or Paul Erdos) creature that is a small number of breeding steps away from a huge set of creature types.
