Negative impacts cloning
However, despite repeated requests by the research community and the news media, Clonaid never provided any evidence to confirm the existence of this clone or the other 12 human clones it purportedly created. These ethical concerns have provoked several nations to pass laws regarding human cloning and its legality.
A deleterious gene that might have been reduced in frequency or eliminated from the population, owing to the death or reduced fertility of the carrier, will now persist in the population and be added to its load of hereditary diseases.
Shortly after that, researchers produced the first genetically identical cows, sheep and chickens by transferring the nucleus of a cell taken from an early embryo into an egg that had been emptied of its nucleus.

Uses of cloning
Unique identities: Cloning raises the question of a moral or human right to an exclusive identity. Gene therapy can be somatic or germ line. How much genetic variation exists in the current human population? In the end, legalizing cloning on a wide-scale basis could lead to a disrespect for human life and the individual worth of a person, which might ultimately diminish all humans in the end. It is not always known how natural selection impacts these traits, but surely it does and does it differently in different parts of the world or at different times, as a consequence of the development of new vaccines, drugs, and medical treatments, and also as a consequence of changes in lifestyle, such as the reduction of the number of smokers or the increase in the rate of obesity in a particular country. This young animal is referred to as a clone. While more than 30 countries formally ban cloning for reproductive purposes, China, England, Israel, Singapore and Sweden do allow cloning for research, but disallow reproductive cloning. Cloning is a common, ongoing, debatable topic among society today. Among the most common chromosomal disorders are Down syndrome, caused by the presence of an extra chromosome 21, and various kinds due to the absence of one sex chromosome or the presence of an extra one, beyond the normal condition of XX for women and XY for men. Another potential problem centers on the relative age of the cloned cell's chromosomes. The richest source of embryonic stem cells is tissue formed during the first five days after the egg has started to divide. Cloning can be done deliberately or naturally; and it results in two copies having identical cells, DNA, genes, organs and organisms. Issues are now raised over the potentially destructive side of this scientific frontier. In other mammals, such as cats, rabbits and mice, the two spindle proteins are spread throughout the egg. The First Cloned Animal: Dolly the Sheep The first successful animal cloning occurred over 22 years ago, after a Scottish Blackface sheep surrogate mother gave birth to Dolly on July 5, , at the Roslin Institute, part of the University of Edinburgh.
Researchers routinely use cloning techniques to make copies of genes that they wish to study. Introduction Technology has advanced by leaps and bounds.
Genetic Disorders More than 2, human diseases and abnormalities that have a genetic causation have been identified in the human population. The possible objectives are to correct the DNA of a defective gene or to insert a new gene that would allow the proper function of the gene or DNA to take place.
However, in addition to the huge economic costs, technical hurdles remain. It has adverse effects on several aspects, for instance social ethics problems and Ecological ethics problems. The treated person can live a more or less normal life, marry, and procreate.

We must encourage research and studies in science. Cloning in the interest of science Cloning refers to the process of creating a genetic copy of a living organism, with the exact same DNA. This can happen naturally in the case of twins , or it can be manmade. Genetic changes i. The common types of cloning is Gene cloning, reproductive cloning, and therapeutic cloning. With the increasing life span of human beings, the concept of cloning human beings for replacement of body parts is abuzz in the science world. Cloning is when two cells decide or are forced to duplicate into two cells to replicate each other. Effects of Cloning While the purpose of cloning is to create an exact replica — if scientists cloned a human that appears identical to the original — it raises the questions as to whether the cloned human is an individual separate from the original and is due the same rights as any other human.
