What is Melanin?

Melanin is a natural skin pigment. Hair, skin, and eye color in people and animals mostly depends on the type and amount of melanin they have. Special skin cells called melanocytes make melanin.

3. Scientists learned that white fur color is fox is the result of a mutation in the gene that codes for melanin. If a fox that lives in the woods in Anne Arundel County is born with this mutation, what prediction can be made about the mutation?
