Albinism
Albinism is a hereditary condition. It is usually inherited in a recessive pattern; it means, both parents have to give the albinism gene to a child to cause albinism. Parents pass on pairs of genes to their children. One of the pairs of genes is in charge of making melanin. If both of these genes are flawed, then little or no pigment is made. If only one gene is flawed then pigment can still be made.
