• A. Nucleus from Scottish blackface ewe was inserted to the egg cell.
• B. Dolly was completely identical to Scottish blackface ewe.
• C. Dolly was given birth by the Scottish blackface ewe.
• D. Dolly did not show any character of the Finn Dorsett sheep.

Answer 1

The correct option is C Dolly was given birth by the Scottish blackface ewe.

• During the cloning process of Dolly, the nucleus from Finn Dorsett sheep was obtained. It was then inserted into the enucleated egg cell of Scottish blackface ewe.
• The produced egg cell was then implanted into the Scottish blackface ewe. Development of this egg occurred normally and finally Dolly was born.
• Dolly was given birth by the Scottish blackface ewe. But it was found to be absolutely identical to the Finn Dorsett sheep. As the nucleus was taken from the Dorsett sheep.
• Since the nucleus from the egg of the Scottish blackface ewe was removed, Dolly did not show any character of the Scottish blackface ewe.
