I believe so, yes! I'd actually be very interested to know if you could grow a different colored eyeball from your liver cell but I don't think it's possible - like for example the brown eyed gene doesn't even exist in a blue eyed person. I think this is the case because in cloning, for example, you make a clone from a single cell by activating ALL the genes, which causes many parts to grow from one cell. If ALL the genes were activated, you would have multiple eye color genes which would fight for dominance, and the brown eye gene, which is dominant, would produce the result. However in the case of animals I haven;t heard of genetic discrepancies such as eye color for example, but no humans have been cloned yet by legitimate sources (cough clonaid cough) so it seems the issue has not been brought to the table yet.
