Question 2

Allele frequency

Answer 2

Measures how common an allele is in a population.

Question 3

Evolution (In genetic terms)

Answer 3

Occurs when there is a change in allele frequency in a population

Question 4

Gene Flow

Answer 4

A change in allele frequency in a population due to the transfer of alleles from one population to another.

Question 5

Genetic Drift

Answer 5

A change in allele frequency in a population due to random sampling

Question 6

Genetic equilibrium

Answer 6

A state in which the allele frequency remains constant Evolution DOES NOT occur

Question 7

Speciation

Answer 7

The process of forming a new species.

Question 8

Reproductive Isolation

Answer 8

Occurs when members of different populations can no longer mate successfully.

Question 9
