Question
The following table shows the number of dogs for certain tail lengths in a population of dogs.
Tail Length Number of Dogs
very short (less than 1 inch) 2
short (1–5 inches) 5
medium (5–10 inches) 15
long (10–15 inches) 5
very long (15–25 inches) 2
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, what type of trait is tail length in dogs?

Based on the data provided, tail length in dogs is best described as **polygenic**. Polygenic traits are those that are influenced by multiple genes and typically exhibit a continuous range of phenotypes, such as height, skin color, and in this case, tail length. The distribution you provided suggests that tail length is not a simple Mendelian trait with discrete phenotypes, but rather a trait influenced by multiple genetic factors, resulting in a varied range of tail lengths observed in the population.
