Normal-looking clones may be genetically abnormal

Scientists have found the first evidence to show that even seemingly normal-looking clones may harbor serious abnormalities affecting gene expression that may not manifest themselves as outward characteristics. The findings, reported in the July 6 issue of Science by researchers at the Whitehead Institute for Biomedical Research and University of Hawaii, confirm the previous suspicion that reproductive cloning is not only inefficient, but may actually be unsafe.
