The idea of ​​cloning an animal was once considered a fictional idea, but was only believed by truly crazy people. Animal cloning has come a long way since Hans Dreisch cloned the very first animal in 1885. There are many different ways and reasons why animal cloning has been done. The range of cloned animals varies from sea urchins, frogs, fish, salamanders, mice to sheep, cows and even dogs and cats. There are different ways to clone animals. The animal can be reproductive, therapeutic or gene cloned. The use of animal cloning has many advantages. Cloning can bring back the population of an endangered species to a sustainable number or even bring back the image of a deceased pet. The once fictitious idea of ​​producing an identical copy of an animal has now become an essential and relatively common practice in ordinary households. Animal cloning is not only a recent milestone for science, but it has been around for centuries. Cloning does not simply refer to the artificial creation of an animal, but can be produced naturally. Identical twins are considered natural clones. Identical twins are produced when a fertilized egg divides into more than one embryo carrying identical DNA. Identical twins may have almost the same genetic makeup as each other, but differ genetically from their parents. (“Cloning”) When cloning does not occur naturally, it must be created artificially. There are several types of cloning that are carried out to produce or modify the future development of an animal. The first type of cloning is reproductive cloning. The process of reproductive cloning is a rather simple process. This type of cloning uses a technique called somatic... middle of paper ... it will be the same in terms of personality. Cloning, which was considered an impossible task, has incredibly now become usable by any capable person. Animal cloning has progressed extremely quickly since the first animal was cloned in 1885. There are many types and reasons why cloning has impacted the scientific community. Cloning can produce multiple offspring from an original egg that would produce only one. It has also been used to combat and replace destroyed tissue and even to restore the image of a long-loved pet. Although cloning remains a difficult endeavor with a success rate of around 5 to 7 percent ("Animal cloning is the last weapon to fight wildlife extinction"), scientists are still trying to improve their cloning capabilities. Animal cloning has affected medical practices and will always benefit the scientific community.
