Should cloning be banned ? Cloning is using genetic engineering to make exact copies of living animals and plants. One of the most famous cloning processes involved a sheep named Dolly. The sheep was the first mammal cloned from adult DNA. Since then it has become part of real life and the subject of public debate. For some people, human cloning is acceptable in medicine in spite of the criticism that it is repulsive. Firstly, cloning the organs can save many lives. For example when a person needs an organ and can not find a donor, doctors could just give her the cloned organ. People would not need to donate their organs anymore. Secondly, parents who can not have children may wish to clone a child for themselves. Also endangered animal or plants could be cloned to rise their species. On the other hand, there are also many arguments againts cloning. Most cloned animals suffer severe medical issues and many...

Over the centuries, mutation produced a wide array of colours based on 2 different pigments. Eumelanin gives the blacks, browns and blues while phaeomelanin gives the reds, fawns and creams. A few other genes give further variations on those colours such silvers, colourpoints and solids/selfs. Mutations continue to occur and unexpected colours also turn up due to inbreeding where recessive genes, hidden for generations, start showing up. AMBER AND LIGHT AMBER During the 1990s, some purebred Norwegian Forest Cats in Sweden produced chocolate/lilac and cinnamon/fawn offspring. However, those colours are not found in the purebred Norwegian Forest Cat gene pool. Had the gene pool become polluted by someone, perhaps generations ago, breeding their Norwegian Forest Cat to another breed? ...
