Nope. Copy, not artificial. The term is actually in established use in botany, for instance, where many plant species reproduce by making copies of themselves.
What are you talking about? Identical twins are just what the term implies -- identical. Their genomes are identical, apart from replication errors (which would show up in clones as well).
Their DNA is identical yes; because they're made from the exact same egg and sperm - but they're rarely, if ever, completely
indistinguishable. Like the scribe writing the pages: using the same hand and the same ink, there will still always be slight differences between them. My point was that neither is a "copy" of the other (as in one came first and the other mimicked). I thought by you comparing it to twins and saying they're clones of each other that I would have to point out that "one isn't following the other or made to imitate" and that they're naturally identical - unlike a clone, in the artificial sense, whereby one is
mimicking the other; it's hard to explain because it seems language is against me.
When you say "copy" or "clone" you usually think one is "original" and the other an "imitation", but having looked up the actual definitions of such words (replica, clone and copy), one needn't be "first" or "original". There is the problem with what I was trying to say. Neither twin is first or second, original or imitation (like Yui and Rei), they both just are
identical. I don't know if I've explained that any better, but it will have to do - for now at least.
Sure it would. In Shinji's mind he knows she's a clone of his mom and is squicked out by the idea of being with her. That's a pretty good way of preventing (romantic) love from happening.
Well, I don't think you can speak on Shinji's behalf, but perhaps (I'm not speaking on his behalf either, it's just hypothetical) the love (romance) he (hypothetically) felt for her before he found out the truth would continue strong - despite his revelation.
