A total of 175 skin grafts were transplanted among 20 individuals belonging to two separate populations of the parthenogenetic lizard Cnemidophorus uniparens. Of these, 98.8 percent were permanently accepted, which indicates that all individuals of each population may be genetically identical. These results further suggest that large populations or the entire species may consist of one clone derived from a single individual.
