In an effort to allay such fears, Wilmut points out that while a cloned child would be a genetically identical twin of the person from whom it was cloned, a cloned human would be influenced by its environment and would develop a distinct personality just as natural twins do.
Et keegi selle pärast muret ei tunneks, märgib Wilmut, et kuigi kloonitud laps on geneetiliselt identne inimesega, kellest ta klooniti, mõjutab klooni tema ümbruskond ning tal areneb teistsugune isiksus, just nagu on lood ka kaksikutega.
