Problem
You are going to clone a hamster named Fluffy. Although you use the same type of hamster for the egg cell donor and the surrogate mother, they are different colors than Fluffy. Fluffy is a tan colored hamster, but after going through the cloning process, Fluffy's "clone" is born and is a dark brown color. Explain an error you could have made in the cloning process that would cause this clone to be dark brown instead of tan.
