Day 4 - Evolution & Ecological Tolerance

Which of the following is an example of natural selection?

• Bald Eagles are hunted until near extinction, population recovers.

• Small group of iguanas floats to an island, starts a new population.

• Red fox pups are more likely to survive in a snowy environment if they are born white.

• Farmer chooses seeds from largest apples to plant next year. This results in larger apples from year to year.

Which statement below is true of mutations

• are intentional, not random, changes in the genetic code

• are never passed on to successive generations

• will never improve an organisms chances of survival

Which statement below would not indicate a bottleneck occurred in a population?

• there are reduced population numbers

• there is lower genetic diversity

If a few individuals from a mainland population colonize an island, which of these is true?

• the genotypes of the island represent all the genotypes in the mainland population

• the genetic diversity on the island will be much greater than the genetic diversity on the mainland

• the island population will be much more susceptible to a disturbance

• the island population will be less susceptible to extinction

This mechanism of evolution occurs when individuals migrate between populations.

• Extinction
• Gene flow
• Genetic drift
• Natural Selection

One day a group of scientists collected a small group of brown anole lizards from a large group of the lizards.  Then they placed this small group of lizards on an island that had no brown anole lizards on it.  What is this an example of?

• Bottleneck Effect
• Hardy Effect
• Founder Effect
• None of These
