I'm not even remotely an expert in this field (my initial
exposure to the subject was an episode of CSI last year),
but I did a brief bit of web-research then, for what it's
worth. I was left with the impression that a chimera is the
result of a mutation or aberration in development; so I
too am quite surprised to find an example of something
that reliably reproduces as a chimera.

I'd think that the seeds would contain one genome or another.
