In what ways does the cloned cat Cc demonstrate the limitations of cloning technology in obtaining desired phenotypes?
What will be an ideal response?
Cc differs in several respects from her somatic cell-donor mother despite being genetically identical. Her coat color differs, as does her shape and personality. These differences stem from various complicating factors, including patterns of X-inactivation and environmental contributions to certain quantitative traits.
