Multiple Choice
Multiple ChoiceCertain dog breeds regularly have “docked” tails, where a dog’s tail is cut to a short length while still a puppy. A breeder of rottweilers tells you that docking has become so common in this breed that they think puppies will start being born with short tails. Evaluate their thinking.
A
Because only dogs with docked tails are reproducing, puppies are likely to be born with short tails.
B
A docked tail would be considered an acquired trait, and therefore, you would not expect it to be inherited.
C
Docked tails will become more common if they help the dogs perform certain tasks.
D
Short tails are unlikely to become common in puppies because a docked tail mainly affects a dog’s appearance.
