A twin is different really because twins still have the DNA of both parents from sexual reproduction, not from cloning process.
Doesn't matter.

I'm not sure but something does interest me. I read somewhere that genetic mutations take place in the cloning process and that it could be lethal that's why clones die off. I can't stop but wonder why this happens and how it could be fixed! lol
Mutations also take place when twins are born naturally. Even idential twins can have a few DNA bases different.

We don't. The reason you have mutations not shared by either of your parents (even though you're not a twin) is because of mutation. This is a natural part of evolution. People will naturally end up with mutations no matter whether they reproduce naturally or are cloned. But attempting to stop the process of evolution is a bad idea. Without evolution doing what it does you would not be here.

Clarification

Mono-Zygotic twins begin their development from a single split egg and therefore with identical dna, clones of each other. Mutations through development account for the slight differences that can sometimes be observed

I have fraternal twins, not from the same egg and therefore not clones and actually as different as chalk and cheese

Yah I don't know where someone here got the information that insects clone. lol

Wow, great question!

May I ask you one? Why don't you study this stuff in greater detail - you have good ideas, the answers are waitingforyou!

It's more complex than that. Humans - well, all animals - have mechanisms to detect deleterious mutations and abort developing fetuses.

Our DNA repairing mechanisms work when the entire system is functioning - in viable phenotypes. When the mutations are too severe, the developing organism self-destructs. Also, when the mutations are too severe, they interfere with the ability of the organism to function; so it dies.

Cloning doesn't quite work like that, though I'm sure those systems are operating, too. The main problems with cloning are lie in teleomere length, if I remember correctly. Teleomeres shorten every time a cell reproduces. When they get too short, cells are no longer viable, and you get cellular death, then organ failure. So in older animals, teleomeres are getting shorter - when you clone them, you've started with old teleomeres, giving the clone a limited lifespan.

I'm sure there's more to it than that, but I'm not super familiar with how cloning works. Part of the problem is where you choose your cell - depending on location, cells have only part of your genes active and most of your genome shut off. So, if you clone from the skin cells you're going to have different problems than if you clone from muscle or stem cells.

And, yes, you might have mutation, though I would guess that would be the rarest problem. The largest problems are the ones I mentioned above, plus that somatic cells are simply not chemically cued to reproduce as germline cells. So various parts of them fail in ways that I am not familiar with.

Yes. Add in environmental differences, such as chemical, nutritional, immune system and so on, gradients in the womb, and different environments after birth. Mutations after cell separation are probably the minor factor for differences, honestly.

For dizogotic twins, environment is what makes them similar, with genes and genetic-environment interaction making them different.

I'm sure you have fun with them!

Is it safe to assume that perhaps a somatic cell or mitochondria of a zygote should be mixed in with the donor's ovum? That means, the donor will have to provide her egg and then be mixed with someone who will actually get pregnant to provide the somatic cell of her growing zygote? The reason being is that the zygote's cells are still fresh as oppose to somatic cell or DNA of an adult that has already undergone complex cell processes including mutations. This will prevent the clone from inheriting damaged cells. The zygote will come from someone else instead of the ovum donor. The idea is that the somatic cell will come from a zygote and an ovum from an adult egg donor. Does it sound unethical? Dolly the sheep had three mothers, the egg donor, the DNA of another, and the surrogate mother. She is not the identical twin of one donor and is genetically different from her.

No. That's not safe to assume. You're basically oversimplifying and therefore on the wrong track. Good guesses for what you know, but not for what is known by biologists who study such things.

Honestly, you have great ideas, a wonderful imagination. Just read the literature on this stuff - you're already interested. I promise you that you will find answers, you'll be utterly amazed and it will change your world. And you may even come up with original ideas and make a genuine contribution.

The truism that I have learned about anything I thought I knew a little about, that I started to learn more about, was that I know nothing about almost everything. There is more to this world than I can imagine, than I can know - and, when you learn more about how cells reproduce, you will understand more than you can understand now.

And it will amaze you.

With 7 billion people and climbing, why do we need to clone to get slaves? Sure it could be doable, but does it make sense as a probable outcome.

I agree. It would have to be raised the same as any child.

My future responses to the clone issue will just be copies of an original, previous response.

I agree. I just realized that getting the somatic cell of a zygote is impossible. If possible, it has to be an embryo or fetus. But that just poses ethical problems. lol

But anyway, I will get more info. You're right I am already interested. I have been interested in human cloning that started ten years ago in college when I did my persuasion speech/presentation in human cloning. I got an A on that! ;-)

second, it's not impossible, it's just difficult.

That's a lot easier :)

There you go! You've got a start!

I tried to find you some stuff to read, but...wow, most cloning seems to take place at the genetic/molecular level, so it's difficult to find 'state of the discipline' articles. Here are two...uh...overviews, I guess:

It would be difficult to have progress in human cloning because it's illegal in the first place.:/
