Question

Dolly sheep was obtained by

• A. Cloning the udder cell (somatic cell) fused with 6 enucleated oocyte
• B. Cloning of gametes
• C. Tissue culture
• D. None of the above

Answer 1

The correct option is A Cloning the udder cell (somatic cell) fused with 6 enucleated oocyte

Dolly is the first sheep which was developed by the technique of cloning. The sheep was developed from the diploid body cell. The somatic cell from the udder of the mother sheep was taken and the nucleus was injected into the enucleated egg cell which was cultured and transferred into the surrogate mother. This method is known as nuclear transfer. The sheep Dolly was identical in the characters with the mother who donated the diploid nucleus from the body cell.

Thus, the correct answer is option A
