Question

A particular breed of dog can have long hair or short hair. When
true-breeding long-haired animals were crossed to true-breeding
short-haired animals, the offspring all had long hair. The F2 generation showed a 3:1 ratio of long- to short-haired offspring. A
second gene affects the texture of the hair. The two variants are
wiry hair and straight hair. F1 offspring from a cross of these two
varieties all had wiry hair, and F2 offspring showed a 3:1 ratio of
wiry-haired to straight-haired puppies. Recently, a breeder of the
short- and wiry-haired dogs found a female puppy that was albino.
Similarly, another breeder of the long- and straight-haired dogs
found a male puppy that was albino. Because the albino trait is always due to a recessive allele, the two breeders got together and
mated the two dogs. Surprisingly, all of the puppies in the litter
had black hair. How can you explain this result?
