Question

In a population of mice, individuals with medium brown fur are less likely to be seen by predators than light brown and dark brown mice. What type of selection is this, and what would the distribution curve for the mouse population look like?(1 point)

Answer 1

This situation describes a form of stabilizing selection. In stabilizing selection, individuals with intermediate traits (in this case, medium brown fur) are favored, while individuals with extreme traits (light brown and dark brown fur) are selected against. As a result, the distribution curve for the mouse population would be characterized by a tall, narrow peak in the center of the graph, corresponding to the favored trait.

Therefore, the correct response is:

stabilizing; a tall, narrow peak in the center of the graph.
