Reproduction is good /in concept/, but it doesn't capture the
mechanism for myself well enough. We create signals from memes in
protocols encoded by memes. Those signals travel. The signal is
interpreted by protocol-memes and the interpreted/created memes are
dumped into the memesphere of the recipient. As I see it, that's the
process. Intermediately, there are no memes at all, just signal.
Looking at it from the biological reproduction perspective removes
consideration of the signal, and thus, the source of the mutation.
Sort of like looking at biological organisms without knowing what DNA
is; a step back.
