As a tangent (please, Artificer, ignore this branch of the thread, as it
deals with an obscure exception to R. Norman's reasonably correct
statement), is there competition within a chimera? It seems that for
each tissue type (which I will leave conveniently undefined), one member
of the chimera dominates it. What mechanisms would tend to make this so?
Simple developmental issues (Jane's blood cell's got there first, so
Jane gets all the blood), immunological issues involved with the
coexistence of two beings, or is it an actual competion between the two
choices for each cell type?
I suspect that competition between the members of a chimera is
inevitable, but I'm interested in others' thoughts.
