Which of the following is an example of the bottle neck effect? Options: 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.

Bald Eagles are hunted until near extinction, population recovers.

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.

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

Five hundred years after the deer had established a flourishing population in the park, a few of them venture back to their original woods and have babies with the deer there. Options: Genetic Drift, Mutations, Non-random mating, Gene flow

Yellow toucan birds seek out one another to make babies together and tend to avoid the green toucan birds.

What is it called when a small group of organisms is placed in a new location where they did not previously exist?

Back

Founder Effect

Front

Structures with the same parts have different functions; suggests that organisms share a common ancestry

Back

homologous structures

Front

Study of embryos of various organisms to show a common ancestor because of similarities in development

Front

Some organisms that share a common ancestor have features that have different functions, but similar structures.
