In many mammals, including rabbits, there is a hair texture known as angora, in which the hair is long and soft. Angora rabbits are highly prized for the quality of their fur. A rabbit breeder has four rabbits: an angora male, an angora female, a short-haired male, and a short-haired female. (The sex of the rabbits is not relevant to the solution.) He made the following crosses with the outcomes shown.

Probability in biology; please help me answer part D. 

In many mammals, including rabbits, there is a hair texture known as angora, in which the hair is long and soft. Angora rabbits are highly prized for the quality of their fur. A rabbit breeder has four rabbits: an angora male, an angora female, a short-haired male, and a short-haired female. (The sex of the rabbits is not relevant to the solution.) He made the following crosses with the outcomes shown. Angora female x angora male = all angora Angora female x short male = all short Short female x angora male = 4 short and 5 angora a. Which phenotype is dominant? b. What are the genotypes of each of the parents? c. If the short female and the short male were mated to each other, what fraction of the offspring is expected to have short hair? d. Even for experts, the sex of rabbits is very difficult to determine, but the breeder wants to keep the males and females separate as much as possible. When the mating in (c) is performed, a litter of five rabbits is born. What is the probability that at least one of the five is a female?
