Chapter 4, Problem 14PDQ

Horses can be cremello (a light cream color), chestnut (a brownish color), or palomino (a golden color with white in the horse’s tail and mane). Of these phenotypes, only palominos never breed true.

1. (a) From the results given above, determine the mode of inheritance by assigning gene symbols and indicating which genotypes yield which phenotypes.
2. (b) Predict the F₁ and F₂ results of many initial matings between cremello and chestnut horses.
