What do you know about twins?
There are twins of the same sex and those of different sexes. The twins here are identical in sex and appearance and are good examples of natural clones. They carry the same genetic information. The fertilized egg has split into two while inside the mother, and so produced two identical human babies.
A clone is an animal or plant
produced naturally or artificially
from the cells of another animal or
plant and is exactly the same as it.
2. How is a clone produced? The cloning of plants is simple and relatively easy. It can be done by taking cuttings (man-made cloning) or letting the plant produce its own runners (natural cloning). The cloning of animals is more complicated. It was not achieved until 1996 and is fully explained in the first reading.
