Albinism (lack of skin pigmentation) is caused by a recessive autosomal allele. Autosomal alleles are those found on chromosomes other than the sex chromosomes. This would be chromosome number 1-22 in humans. A man and woman, both normally pigmented, together have an albino child. P = allele for pigmentation, p = allele for albinism.
