This won't be answered for a long time. Scientists are barely able to clone a sheep and have it live, their not close to being able to tell if they can have say "a rabbit be born from a sheep" ... It's a good start though, maybe EVENTUALLY!
I think you're going to have to be a little more specific - which animal? All species have different gestation periods.
No, because when you clone an animal of some sort, you are taking a nucleus of one of its cells and implanting it in another mammal's reproductive system (i.e. womb) where it will grow. When it is born, it will be the clone of the mammal you took the cell's nucleus from. However, there are some negative affects. When you clone an animal, that animal might have bone problems, sicknesses, and diseases than the usual amount of problems it might have when it is NOT a clone.
Identical siblings right at birth/in the womb
Animal cloning is a very complicated scientific process that has taken years to develop. Unfertilized eggs from a female animal are collected and the genetic material is removed. Next, genetic material from the clone's donor is injected into the egg. The egg is given an electrical shock which makes it begin to grow and divide. The dividing cells form into an embryo. The embryo is then transplanted into the womb of a surrogate animal mother, who will give birth the cloned animal.
Ovulation is when an egg in a woman or female animal is released and goes into the womb of a female of the species. When the egg is released the female can become pregnant.
Fish do not carry offspring in a womb. They lay eggs. The amount of time spent in the egg varies from species to species.
a baby
The disadvantages to having a clone are no different than those of having a normal child, or in the case of being cloned while in the womb, no different than having an identical twin.
They can. Just as human siblings can have different hair color or diffierent colored eyes, so too can horses.
The womb is going to symbolize different things to different people. For some it represents safety, for others it represents life.
Your question is very broad. First, are you talking about sexual reproduction or about farming? Secondly, if it is sexual reproduction, what species? Different species have very different details of how and where fertilization takes place.
A placenta, a belly button, a womb.
