18. 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 consisted of a 3: 1 ratio of long- to short-haired animals. 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- to straight-haired puppies. recently, a breeder of the short-, wiry-haired dogs discovered a female puppy that was albino. similarly, another breeder of the long-, straight-haired dogs found a male puppy that was albino. the albino trait is due to a recessive allele. the two breeders got together and mated the two dogs. surprisingly, all the puppies in the litter had black hair. how would you explain this result
