Chapter 3, Problem 21P

A black mare was crossed to a chestnut stallion and produced a bay son and a bay daughter. The two offspring were mated to each other several times, and they produced offspring of four different coat colors: black, bay, chestnut, and liver. Crossing a liver grandson back to the black mare gave a black foal, and crossing a liver granddaughter back to the chestnut stallion gave a chestnut foal. Explain how coat color is being inherited in these horses.

In horses, B=black coat, b=brown coat, T=trotter, and t=pacer.  A black pacer mated to a brown trotter produces a black trotter offspring.  What is the genotype for this offspring.
Potatoes may have the following shapes: long, round, or oval. The cross between long and oval potatoes yielded 209 long and 216 ovals. While the cross between oval and round potatoes yielded 213 oval and 209 round. Crosses between long and round potatoes yielded 600 ovals. Lastly the cross between two oval potatoes yielded 201 long, 313 ovals, and 209 round. What is their inheritance?
When a white guinea pig is crossed to a yellow guinea pig, all the progeny are cream colored. From a cross of two such F1’s, the F2 showed 32 white, 66 cream, and 30 yellow guinea pigs. How is this trait inherited?
