Classic albinism is an autosomal recessive mutation. However, two parents with albinism may produce a child with normal pigment. How can this be so?

There are a number of biochemical steps in melanin biosynthesis from tyrosine. For this reason, albinism can be caused by different enzyme deficiencies at different steps of the pathway. If each of the parents' albinism stems from a different enzyme deficiency, they can therefore have a child with normal pigment.
