What concept explains the cloning of identical twin puppies from a single muscle cell?

• A. The cloning is consistent with the idea that the genomes of all somatic cells within one animal are the same
• B. The cloning is consistent with the idea that the genomes of all cells within one animal are the same
• C. The cloning is consistent with the idea that the genomes of all somatic cells within an animal species are the same
• D. The cloning is consistent with the idea that the genomes of all cells within an animal species are the same

Answer: (A)

The concept that supports the cloning of identical twin puppies from a single muscle cell is rooted in the idea that all somatic cells within one animal possess the same genome. This means that the genetic material in every cell, excluding gametes (sperm and egg cells), is identical. When cloning occurs, scientists can take DNA from a somatic cell, such as a muscle cell, and use it to create a new organism, as that DNA contains the complete set of genetic instructions necessary to develop into a fully functional animal. In this scenario, the cloned puppies share the same genetic makeup because they originate from the same muscle cell, which dictated their specific traits and characteristics. Therefore, the cloning process reaffirms the principle that within a single animal, the somatic cells do not differ genetically; they all carry the same DNA. This is why the concept specifically focuses on somatic cells within one individual rather than across different individuals or species, which is addressed in other options but does not apply to this cloning instance.
