- 1. Multiple Choice
Tail length in dogs is often determined by incomplete dominance. Pups of long-tailed (TT) and short-tailed (SS) parents often split the difference and have medium-length tails (TS). If we crossed two heterozygous dogs what is the probability that the offspring would have long-length tails?
