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?
