A bar graph entitled Dog Tail Length in a Population. The Y axis is labeled Length (inches). Two dogs have very short tails, less than one inch. Five dogs have short tails, between one and five inches. Fifteen dogs have medium-length tails, between five and ten inches. Five dogs have long tails, between ten and fifteen inches. Two dogs have very long tails, between fifteen and twenty-five inches.

Based on the data provided on the tail lengths of dogs, tail length is considered a polygenic trait.
Polygenic traits are influenced by multiple genes, which contribute to a continuous range of phenotypes. The variation in tail lengths among the dogs, as shown in the table with different categories, suggests that there are multiple genetic factors at play determining the tail length, making it a polygenic trait.
Therefore, the correct response is polygenic.
