The genetic disease blue sclera is determined by an autosomal dominant allele. The eyes of individuals with this allele have bluish sclera. These same individuals may also suffer from fragile bones and deafness. This is an example of

Blue sclera is a result of a pleiotropic gene, as it has multiple effects on an individual's phenotype, such as fragile bones and deafness. Autosomal dominant inheritance indicates that an affected individual only needs one copy of the allele for the disease to be present, rather than both copies. Incomplete dominance, codominance, epistasis, and linkage do not fit the observations in this scenario as well as pleiotropy.
