Ibinism is an autosomal (not sex-linked) recessive trait. A man and woman are both of normal pigmentation and have one child ut of three who is albino (without melanin pigmentation). What are the genotypes of the albino's parents? One parent must be homozygous for the recessive allele; the other parent can be homozygous dominant, homozygous recessive, or heterozygous. Both parents must be homozygous dominant. One parent must be heterozygous; the other parent can be homozygous dominant, homozygous recessive, or heterozygous. Both parents must be heterozygous. One parent must be homozygous dominant; the other parent must be heterozygous.
