The dif
3、ferences in the two cats indicate that identical DNA wont necessarily create similar appearances or personalities because there are many other factors that contribute to both surface characteristics and temperament(性情)CC has since gone on to have three healthy kittens via the natural method, and the
4、 research that led to her creation became the foundation for a Californiabased pet cloning company called Genetic Savings & Clone, Inc.However, the cat cloning project caused criticism from animal welfare groups, which pointed out that millions of cats are killed in shelters each year due to pet ove
5、rpopulation.They argued that the large sums of money spent on creating more cats could be put to better use providing homes for strays.There are also objections to the cloning process itself.Many people consider cloning cruel, as it is a process that can lead to deformities and other problems, which
6、 is evident in the fact that many clones die within months or even days of creation.Much to the delight of animal welfare advocates, after cloning five cats in total, Genetic Savings & Clone shut down in 2006.The reason for the companys close was its inability to make its cloning technology affordab

38、r meat. 16 However, this practice is very controversial, and livestock farmers have been hesitant to adopt it fully because of public opposition and certain inefficiencies.In technical terms, livestock are cloned by taking cells from one animal and using them to fertilize eggs (使卵子受精). Scientists ta

41、genetically (在基因方面)identical or similar, this sort of disease could totally destroy an entire generation of livestock, leaving the world with a massive food shortage.In addition to concerns about genetic diversity, there are other concerns about cloning. 20 There are also some people who worry that
42、livestock cloning research may be a gateway to introducing human cloning, which is widely disapproved of.AAre the surviving clones really clones?BTherefore, the new species is expected to be better.CThe biggest one arises from a reduction in genetic diversity.DCloned livestock have the potential to
43、provide some major benefits.ECloning animals shows us what might happen if we try to clone humans.FThese concerns sometimes come from worries over unforeseen consequences.GThis process doesnt always work perfectly, and it can be relatively expensive.【语篇解读】本文是说明文。文章介绍了动物克隆技术。16B根据上一句内容可知，如果能克隆出生产更多奶和
