For a long time scientists have experimented with cloning. Cloning is creating
an exact copy of an organism. So far, scientists have made some successful animal clones, but much is still unknown about
it. Is cloning right? Will we ever clone humans? Genetics has a large effect on cloning because a large part of the process
relies on taking apart genes. At the rate we're going, cloning could become a large problem in the next few decades. Take
the next example into account:
As heard on the news in the past years, scientists have been busy trying
to clone animals, such as cows. Cloning is very complex yet simple. Basically, only female animals can be cloned. To clone
you need two X chromosomes from the test subject and let it be fertilized into an exact copy of the 'mother'.
In normal reproduction, an X chromosome from the female must be fertilized
by an X or Y chromosome from the male. When the female gives birth, the offspring looks half like the mother, and half
like the father.
