Palomino horses have a golden yellow coat, chestnut horses have a brown coat, and cremello horses have a coat that is almost white. A series of crosses between the three different types of horses produced the following offspring:

Palomino x Palomino 13 Palomino, 6 Chestnut, 5 Cremello
Chestnut x Chestnut 16 Chestnut
Cremello x Cremello 13 Cremello
Palomino x Chestnut 10 Palomino, 12 Chestnut
Palomino x Cremello 8 Palomino, 9 Cremello
Chestnut x Cremello 26 Palomino

1.What is the mode of inheritance of Palomino, Chestnut, and Cremello?
2.How many genes are involved?
3.Assign symbols for the alleles that determines these phenotypes.
4.List the genotypes for each phenotype.
