The following coat colors are determined by alleles at one locus in horses:
palomino = golden coat with lighter mane and tail
cremello = almost white
chestnut = brown

The following table gives ratios obtained in matings of the above varieties:

Cross

Parents

Offspring

1 cremello × cremello

all cremello

2 chestnut × chestnut

all chestnut

3 cremello × chestnut

all palomino

4 palomino × palomino

1/4 = chestnut

1/2 = palomino

1/4 = cremello

Assign gene symbols for the genetic control of coat color on the basis of these data. Diagram the last two matings.
