Horses can be cremello (a light cream color), chestnut (a reddish-brown color), or palomino (a golden color with white in the mane and tail). Of these phenotypes, only palominos never breed true. The following results have been observed: Cremello x palomino > 50% cremello, 50% palomino Chestnut x palomino > 50% chestnut, 50% palomino Palomino x palomino > 25% chestnut, 50% palomino, 25% cremello From these results, determine the appropriate allele symbols and indicate which genotypes lead to which phenotypes. Predict the F1 and F2 phenotype ratios of a cremello x chestnut P generation cross.

Question
- Horses can be cremello (a light cream color), chestnut (a reddish-brown color), or palomino (a golden color with white in the mane and tail). Of these
phenotypes , only palominos never breed true. The following results have been observed:
Cremello x palomino > 50% cremello, 50% palomino
Chestnut x palomino > 50% chestnut, 50% palomino
Palomino x palomino > 25% chestnut, 50% palomino, 25% cremello
- From these results, determine the appropriate allele symbols and indicate which genotypes lead to which phenotypes.
- Predict the F1 and F2 phenotype ratios of a cremello x chestnut P generation cross.
