Commercial production of valuable animals of known pedigree can be done by?

Explanation

Cloning is the process of producing genetically identical individuals, which is ideal for the commercial production of valuable animals with a known pedigree. It ensures that the desirable traits of the original animal are preserved in the clone. Genetic engineering involves modifying genes, which may not result in identical animals. Tissue culture is not a method used for animals and is more associated with plant propagation. Gene therapy focuses on treating genetic disorders rather than producing animals with specific pedigrees.
