problem.The eggs can clone into multiple for
fertilization,which greatly improve pregnancy
rate.Disadvantages:1) cloning would reduce the geic variation,through cloning produces the individual has the same geic,the same diseases sensitivity,a disease could destroy the generated by cloning of groups.Can imagine,if one country herds will have the same cloning product,a lesevere virus could destroy the national husbandry.2) cloning technology use will make people tend to multiply the existing population of the most value of the individual,rather than by natural laws to promote the whole population of the muck.In this sense,the cloning technology to interfere with the natural evolution process.3) cloning technology is an expensive technology,need a lot of money and biological professional participation,failure rate is very high.Dolly is 277 experiments only results.Although now developed more advanced technology,the suerate was only to reach 2-3%.4) transgenic animals raised the risk of infection.For example,if a drug milk cow production
infected with virus,which may be through milk infection patients 5) cloning technology applied to the human body will lead to the offspring of artificial control geic traits.Cloning technology debate whether to allow the core is the development of early human embryos for geic operation.This is many ethicists not aeptable.6) cloning
