18. A particular breed of dog can have long hair or short hair. When true-breeding long-haired animals were crossed to true-bree
ding 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
They all explain it, honestly, but B sounds the least like an answer they would accept as true. It's also kind of sus that they have 2 different answers about reacting differently to stress, and B is definitely the least likely of the two to be correct. Sorry I couldn't be more helpful, I'm only here because I searched for the answer myself. Good luck.
