Answer 1

There are some rare endangered animal, country has the giant panda, dolphin and so on. Cloning technology can use them? The pair of pandas for cloning problems, has caused controversy among scientists concerned, then, cloning of endangered animal also exist what difficulty? These difficulties there may be overcome? The difficulty is in endangered species of wild animal animal compared to ordinary world, present a minimal amount of available for cloning experiments, individual is less. The baiji as an example, the remaining also foot 100, Wuhan dolphin hall wife raise " cake ", is available to scientists cloning experiments on a few individuals, but it is a male, even if successful cloning, finally the clone son may also be governed by it to do "" surrogate mother ". Dolly's birth process, scientists used a total of 3 " false mother ", use a total of 277 embryos will succeed in the end. The difficulties of two so far, there are many endangered wild animal growth process, living habits and to grasp. The class has been successfully cloned sheep, rabbits, pigs, monkeys and other animal, for they live well, cloning of these animal course than cloning of wild animal much easier, the success rate is much greater. Difficult three some endangered animal 's special living environment, caused scientists clone their process will encounter many thought. For example, because it is a streamlined life in the water, it lives in the land of Ganges RIv er sheep, monkey, living environment is the same, so cloning experiments, the process, technical difficulty of operation will increase. Therefore, due to save these difficulties, in theory, although cloning endangered wild animal is feasible, but, depending on the cloning technology to save endangered animal the possibility is very small. However, with the cloning of progress and development, believe scientists will gradually overcome some difficulties, let the cloning of endangered wild animal ideal truly, make these precious animal classes become friends, let them long to become a part of the world
