Question

The cloning of Dolly the sheep __________,a. demonstrated that differentiated cells contain only a fraction of their full genetic potential. b. demonstrated that the nuclei from differentiated mammalian cells can retain their full genetic potential. c. demonstrated, for the first time, that eggs are haploid and body cells are diploid. d. revealed that cloned mammals most resemble the egg donor.

Answer 1

Answer:

B) demonstrated that the nuclei from all the differentiated mammalian cells can retain their full genetic potential.

Explanation:

Every cell of an organism contain equal number of chromosomes, like nerve cell, mammary gland cell, muscle cell, heart cell etc. all have same number of chromosome and equal amount of DNA. The morphology and functioning of different cell depends on the differential gene expression.

Cell express their genes according to the requirement or the environment or according to the signals.

The cloning of Dolly demonstrated that the nuclei from all the various  differentiated mammalian cells can retain their full genetic potential.
