Now a day, people will do anything to maybe make themselves live longer, make themselves healthier, or try anything else, especially if it benefits them or their children. Then along came the idea of cloning. What if would you say if someone told you, that you could clone your pet so you would never lose it even if the original one died? What would you say? Well, some people have put that very idea out there, and they’ve made it work. All this sounds great, but the downsides of cloning are rarely looked at, and cloning isn’t as easier as just pressing the copy button.
Cloning is the creation of a genetically identical organism from a cell taken from a host (the genetic parent) and grown in to the younger version of the organism inside a surrogate mother. The process of cloning involves taking a cell nucleus from the organism donor cell, the one you want copied, and putting it into a recipient cell, usually an egg cell taken from the same type of organism soon after ovulation. During this process, the genes are swapping, and not all of them are being reconnected.
When an offspring is created, it gets both maternal and paternal genes. Thus making it unique, but similar in the way that it has characteristics from both the mother and father from which they were created. When making a clone however, the offspring gets genes from only one parent, and all those genes are directly put into the cell to grown the clone. Which in the end results in an exact copy of the single parent. In regular reproduction, the DNA from both parents goes through a process called imprinting. Imprinting is a process where all the genes are marked so only one copy, either maternal or paternal, is turned on. That way the offspring has characteristics from both parents, but may only slightly resemble either one of them. In cloning, since the offspring is only getting genes from one parent, imprinting does not occur and all the genes are turned on. Thus resulting in the exact...
