Dolly the cloned sheep has given birth to three lambs at the Roslin Institute in Edinburgh. Dolly's first pregnancy resulted in just one lamb born in April last year. All the lambs were conceived naturally and all have the same father, a Welsh mountain ram called David. Dr Harry Griffin, assistant director at Roslin said the births demonstrated that the cloning method used to produce Dolly had not affected her ability to reproduce normally and produce healthy offspring.
PPL therapeutics, the commercial arm of the Roslin Institute, where Dolly was created, is planning a similar experiment on rabbits. An unnamed US biotech partner wants to try out PPL's patented technique in the hopes of finding an antibiotic that can kill penicillin-resistant bacteria.
