Natural Selection

Why are advantageous traits more likely to be passed onto offspring?

• Because they are more likely to SURVIVE and REPRODUCE.

• Because they come from dominant alleles.

What is most likely to happen to moth populations in the picture shown?

• Light moths--hunted easily, dark moths--population increase

• Dark moths--hunted easily, dark moths--population increase

• Lights moths will change their color to match dark moths.

In recent years "SuperBugs" (bacteria that aren't effected by antibiotics) are becoming more and more common. How could natural selection explain this?

• Superbugs SURVIVE antibiotics and REPRODUCE

• We have always had the same amount of superbugs; modern media just discusses them more.

• There is no reliable data on the origin of super bugs.

Heredity is:

• The passing of genetic traits from parent to offspring

• Believing in false gods

• Unexplained

Why are advantageous traits more likely to be passed onto offspring?

• Because they are more likely to survive and reproduce.
• Because they come from dominant alleles.

What word describes the PROCESS of having the advantageous traits that helps an organism survive and reproduce?

• natural selection

• genetic engineering

Any inherited trait that is USEFUL to the organism an give them an ADVANTAGE to survive in its environment.

• an adaptation

• evolution

• natural selection

Which of the following best illustrates natural selection?

• An organism with favorable genetic variations will tend to survive and breed successfully.

• A population monopolizes all of the resources in its habitat, forcing other species to migrate.

• The largest organisms in a species receive the only breeding opportunities.
