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 stabilizing; a tall, narrow peak in the center of the graph stabilizing; 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 disruptive; a tall, narrow peak in the center of the graph disruptive; 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 scenario is stabilizing selection. This occurs when individuals with intermediate traits (in this case, medium brown fur) have a higher fitness than those with extreme traits (light brown and dark brown mice).

The distribution curve for the mouse population would look like a tall, narrow peak in the center of the graph, representing that medium brown mice are favored over the extremes. So, the correct response is:

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