Many members of the Fugate family in Kentucky are blue -- the color of their skin not the content of their mood. Blue skin is caused by a mutation in the CYB5R3 gene, with CYB5R3Drepresenting the dominant allele and CYB5R3r representing the recessive allele. The Fugate family is of European origin, and parents of blue children usually have white skin color. (see: Trost, C. 1982. The Blue People of Troublesome Creek. Science 82: 35-39.)
Based on this information, blue skin is inherited as a:
a) Dominant allele
b) Recessive allele
c) Too little information given to tell
