beskrivelse:

1. The mouse population has a majority with light fur, which is very visible, and a minority with dark fur, which is not very visible. At the same time, the owl population has a minority with very good eyesight. The majority have normal eyesight.

2. Mice with light fur were hunted by both types of owl, causing a decline in the light mouse population. As a result, the owl population grew. As they were already the majority, owls without good eyesight remained the majority.

3. Due to their success in hiding from owls, dark mice survive and become the majority. Since the light mice population has been greatly reduced, the owls with poor eyesight are unable to hunt. Owls with good eyesight can hunt dark mice, so they survive and reproduce.

4. Dark mice are not very visible, so they have a better chance of surviving than light mice. Thus they pass on their genes and mice with dark fur becomes normal. Likewise, owls with good eyesight are able to hunt these dark mice, so owls with good eyes are able to hunt and reproduce. Owls with good eyes become normal.
