In the wild mice population described in the source text about populations, traits, and variations, complete the statement: "In this population, black fur and brown fur are ________ of the fur color ________." (A) variations . . . trait (B) traits . . . variation
Imagine a population of wild mice in which each mouse has either black fur or brown fur. (Image: mice from the population)
A) variations... trait. Black fur and brown fur are different forms (variations) of the same characteristic, the fur color trait.
What the statement is really asking
You need to decide whether “black fur” and “brown fur” are the overall characteristic (a trait) or the different versions of that characteristic (variations).
Identify the trait first
The source text says a trait is a characteristic of individuals in a population. Here, the characteristic being discussed is fur color, so fur color is the trait.
Decide what black and brown fur represent
Within the trait “fur color,” individual mice can have different forms of that trait. Those different forms are called variations.
So, black fur and brown fur are variations of the fur color trait.
Quick check with the definitions
- Variation: differences in a trait within a population
- Trait: the characteristic itself
That matches choice (A).
