I watched a documentary where they cloned a horse, it wasn't exactly the same, they had several phenotype differences and also different personalities which were developed according to their breeding. At this moment, the "perfect" cloning is not yet available, but we are heading to the future, and it will be very helpful to clone animals. Also in the future, scientists are expecting to "recreate" people that already died by using their DNA, this sounds very crazy, but maybe we will be able to see Michael Jackson dancing thriller again in some years.
You're absolutely right, the 'perfect' clones are not yet available, genetics is still advancing.
Now I don't know how I feel about recreating dead people from their DNA, it kinda sounds like zombification. Even if it'll all goes according to plan, seeing Michael Jackson again, will create a whole range of emotional responses from people. Many won't be thrilled.
But it will be great to see how things play out at the end.
