Evolution Quiz

What do we call the traits species have evolved over time to help them survive?

During the process of natural selection, what determines which organisms survive and reproduce?

How does natural variation (differences between genotype/phenotype between individuals) affect evolution?

If all organisms share a common ancestor, why aren't we all the same?

• Genetic Variation

• Mutations

• Lateral gene transfer

• All of these have contributed to genetic diversity

How are bacteria becoming resistant to antibiotics?

• Bacteria are being given medications

• Bacteria are evolving

• Bacteria are just built different

• Bacteria have always been resistant to antibiotics

What is a gene pool?

• All available RNA for traits in a species

• All available alleles for traits in a population

• All available alleles for traits in a species

• All available RNA for traits in a population

True or false: All mutations are bad for organisms.

• True

• False

What is it called when a trait is controlled by more than one gene?

Explain what the term allele frequency means.

Explain what determines the number of phenotypes for a given trait.
