Question

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) Responses disruptive; a tall, narrow peak in the center of the graph disruptive; a tall, narrow peak in the center of the graph disruptive; two peaks at either end of the graph with a dip in the middle disruptive; two peaks at either end of the graph with a dip in the middle stabilizing; a tall, narrow peak in the center of the graph stabilizing; a tall, narrow peak in the center of the graph stabilizing; two peaks at either end of the graph with a dip in the middle

Answer 1

The type of selection described in your question is stabilizing selection. In this case, medium brown fur provides a survival advantage, whereas both light brown and dark brown fur are less favorable, leading to a decrease in those traits over time.

The distribution curve for the mouse population under stabilizing selection would be a tall, narrow peak in the center of the graph, indicating that most individuals have medium brown fur, while there are fewer individuals with light or dark brown fur.

Thus, the correct response is: stabilizing; a tall, narrow peak in the center of the graph.
