Predict what will happen to the rabbit population in this environment.

• The rabbits will become extinct.

• Rabbits with brown fur will survive and reproduce more than rabbits with white fur.

• Rabbits with white fur will survive and reproduce more than rabbits with brown fur.

• Rabbits with big teeth will survive and reproduce more than rabbits with small teeth.

In this picture, the selecting factor in the environment is

• fur color

• predator

• tough food

• long teeth

In this picture, the genetic variation in the rabbit population that has a survival advantage is

• fur color

• predator

• tough food

• long teeth

Tags

NGSS.MS-LS4-4

In the simulation, which variation had no advantage but was a random mutation

• fur color (brown or white)

• ear type (straight or floppy)

• teeth (long or short)

In this scenario, the rabbit population will evolve by

• increasing the percentage that have white fur ONLY

• increasing the percentage that have long teeth ONLY

• increasing the percentage that have white fur and long teeth

• increasing the percentage that have white fur, long teeth and floppy ears
