PPL produces cloned calf


PPL Therapeutics has cloned a bull-calf called Mr Jefferson. The same company produced Dolly the sheep.


The calf was cloned from an embryos cell, unlike Dolly who was a clone of an adult sheep.


Mr Jefferson is a 981b Holstein. PPL plans to produce cows whose milk contains human serum albumin, a component of blood.
