Peacock tail feathers can be as wide as 5 feet. Peacock tail feathers are called a train.. KEY CONCEPT:. . Mutations. are changes in genetic material.. VOCABULARY:. Mutation, point mutation, . frameshift. mutation, polyploidy. Mutations – extension from gene expression. . Changes in genotype. If the enzyme that converts tyrosine to melanin is defective, no melanin is produced and a genetic disease known as albinism results.. A peacock with albinism does not produce the melanin needed to make the bright colors of its feathers..
