277 to 1: The Cloning of Dolly
This work refers to the of cloning Dolly the sheep in 1996 in Scotland which required the extraction of 277 mammary cells from an adult ewe to produce one live cloned offspring. See the "just the facts" and "cloning" pages elsewhere on this site to learn about the process.

248 embryos (blue) died after extraction but before fertilization

Dolly as an adult ewe.  She was born in 1996 and died at age 6 in 2002.

16 of the surviving embryos were not successfully implanted in the surrogate mother ewes.

Of the remaining 13 that were successfully implanted, only 1 resulted in a live, healthy offspring.

This installation was designed for the Wellfleet Public Library and shown in 2004.  However, it has many possible configurations for other spaces.
