In the Palomino horses color is determined by three alleles at a single locus; C+/C+(light chestnut), C+/Ccr (Palomino), Ccr/Ccr (cremello). Chestnut is dominant over Palomino and cremello, and Palomino is dominant over cremello (C+/C+> C+/Ccr> Ccr/Ccr). What will be expected phenotypes and ratios of offspring produced by the C+C+/CcrCcr X C+Ccr/CcrCcr crosses?

A family in which club foot was inherited as an autosomal dominant trait. They discovered a mutation in the PITXI gene that caused club foot in this family. Through DNA testing, they determined that 11 people in the family carried the PITXI mutation, but only 8 of these people had club foot. Which of the following is the correct interpretation of the observation?

The type of plumage found in mallard ducks is determined by three alleles at a single locus: MR, which encodes restricted plumage; M, which encodes mallard plumage; and md, which encodes dusky plumage. The restricted phenotype is dominant over mallard and dusky; mallard is dominant over dusky (MR > M > md). The expected phenotypes and proportions of offspring is 3/4 restricted, 1/4 mallard by which of the following crosses?
