反对克隆的原因和赞同克隆的原因，还要有自己的观点
Wethuin＇ experience with cloning animal leave him upet by all thi talk of human cloning. In three year of work on the Miy project， uing hundred upon hundred of dog＇ egg， the A&M team ha produced only a dozen or o embryo (胚胎) carrying Miy＇ DNA. None have urvived the tranfer to a urrogate mother. The watage of egg and the many pontaneouly aborted fetue (胎) may be acceptable when you＇re dealing with cat or bull， he argue， but not with human. "Cloning i incredibly inefficient， and alo dangerou，" he ay.
Even o， dog cloning i a commercial opportunity， with a nice reearch payoff. Ever ince Dolly the heep wa cloned in 1997， Wethuin＇ phone ha been ringing with people calling in hope of duplicating their cat and dog， cattle and hore. "A lot of people want to clone pet， epecially if the price i right，" ay Wethuin. Cot i no obtacle for Miy＇ myteriou billionaire owner; he＇ put up $3.7 million o far to fund A&M＇ reearch.
Contrary to ome media report， Miy i not dead. The owner want a twin to carry on Miy＇ fine qualitie after he doe die. The prototype i， by all account， athletic， good-natured and upermart. Miy＇ mater doe not expect an exact copy of her. He know her clone may not have her temperament. In a tatement of purpoe， Miy＇ owner and the A&M team ay they are "both looking forward to tudying the way that her clone differ from Miy."WWw.hAOZUowEN.com
Beide cloning a great dog， the project may contribute inight into the old quetion of nature v. nurture. It could alo lead to the cloning of pecial recue dog and many endangered animal.
However， Wethuin i cautiou about hi work. He know that even if he get a dog pregnant， the offpring， hould they urvive， will face the problem hown at birth by other cloned animal: abnormalitie like immature lung and heart and weight problem~ "Why would you ever want to clone human，" Wethuin ak， "when we＇re not even cloe to getting it worked out in animal yet?
