Open in App
Solution

  • Cloning is the method of production of genetically and morphologically identical copies of their parents.
  • Dolly was the first mammal to be cloned successfully.
  • In the process of cloning Dolly, the nucleus from the mammary cell of white Finn Dorsett sheep was first removed and then an unfertilised egg cell from Black ewe was enucleated.
  • The nucleus of the mammary cell of the white sheep was then added to the enucleated egg cell of the Black ewe.
  • This hybrid egg cell was then allowed to develop into an embryo.
  • The embryo was further transferred into Black ewe to develop into a newborn sheep named as "Dolly".
