Clones are direct genetic replicas of existing organisms and, therefore, have the same genetic parents as the donor who contributed the sample of DNA used in the process. According to HowStuffWorks, the most promising method for human reproductive cloning is somatic cell nuclear transfer (SCNT). This method delivers a full genome from donor to clone without alteration, thus preserving the genetic legacy of the donor's parents.
Parenting has many definitions, but in the strictest sense, parents are the two individuals who contributed genetic material to form the unique genome of an individual. As this genome is passed unaltered to a clone, it is appropriate to describe the donor's parents as also being the parents of the clone. Once conceived, however, the clone embryo must be implanted via in vitro procedures into a host mother, according to HowStuffWorks. This mother, whether genetically related to the clone or not, could also be regarded as a parent by virtue of gestating the fetus.
Finally, perhaps the loosest definition of parent applies to any older figure who acts to care for a growing child. By this definition, a cloned child can easily identify any adult as a parent, including the donor, who would be a genetic twin of the clone.
