Albinism in animals is caused by recessive mutations in an autosomal gene required for synthesis of melanin, a chemical precursor for skin and eye pigments. albino animals are often confused with so-called leucistic animals that are white due to recessive mutations in a gene required in a different pathway, for example a pathway for development of the cells that produce pigments. suppose you have two white hummingbirds—a male and female—and they mated. assuming that all relevant mutations are rare, autosomal, and recessive to wild-type alleles, what would you expect their progeny to look like under the following conditions: a. they are both albinos. b. they are both leucistic. c. one is albino and the other is leucistic.
