The disadvantages of cloning include increased risk of inherited diseases, lack of gene variation, ethics and religious dogma associated with it. The term cloning refers to a number of processes used in producing genetically identical copies of a biological entity.
Increased risk of inherited diseases stems from the fact that all clones share the same genes and thus may be susceptible to a particular type of disease. This may result in one disease wiping out a whole population. Another disadvantage is lack of gene variation. Natural reproduction ensures a combination of different genes resulting in unique individuals.
The cloning debate has attracted opinions across all spheres. Among the religious circle, for instance, it remains a controversial topic. Most governments have been noncommittal in fully embracing cloning for fear of backlash from the electorate.
