Bull Is First Large Mammal ‘Serial Clone’

A clone of a cloned prized bull thrives today on a Japanese farm, living proof that “serial cloning” can successfully create life beyond mice, according to a report in the journal Nature Biotechnology.
The second-generation cloning that created the black bull named Kamitakafuku took place in 2000, but wasn’t announced until now because researchers wanted to ensure the bull matured and was healthy. The only other mammals known to have been cloned from a clone are mice.
