Dolly the sheep to be mum again

Dolly with her first lamb, Bonny - soon to have a brother or sister

Dolly the sheep, the world's first mammal cloned from an adult cell, is about to give birth to her second lamb.

Scientists at The Roslin Institute in Edinburgh say the birth is due "in a few days".

They said "appropriate information" would be made available in due course, but added they expect less public attention on the birth this time around.

They are not planning to give her second offspring a name.

Dolly was born in July 1996 at the Roslin Institute, after being cloned from a breast cell taken from an adult ewe.

Her first lamb, Bonny, was born on 13 April last year after Dolly was mated the previous November with a Welsh Mountain ram called David.

First lamb 'perfectly healthy'

Bonny is said to be fit and healthy, but too young to breed at present.

Dolly's creators said it is important to breed from cloned animals to check for any unexpected changes in their offspring.

The Institute's Professor Ian Wilmut said none have so far been detected in Bonny, who is a "perfectly healthy" animal.

Dolly was named by the Roslin Institute scientists after the country and western singer Dolly Parton.
