NEET Biology: Biotechnology questions with solutions

Q1. Dolly was given birth by

1. Finn dorset sheep
2. Scottish blackface ewe
3. Polled Dorset sheep
4. None of these

Answer: Scottish blackface ewe

Dolly was cloned using a nucleus from an adult mammary cell, and the embryo was carried to term by a Scottish blackface ewe as the surrogate mother. The birth mother was therefore the Scottish blackface ewe, not the sheep that donated the genetic material.
