Question 1

bottleneck effect

Answer 1

The reduction in genetic diversity that occurs when a large proportion of a population is removed due to a chance event.

Question 2

founder effect

Answer 2

The reduction in genetic diversity that occurs when a population is derived from a small unrepresentative sample of the original population.

Question 3

founder effect

Answer 3

The reduction in genetic diversity that occurs when a population is derived from a small unrepresentative sample of the original population.

unrepresentative sample

Answer 4

A small selection of individuals from a larger group that does not reflect the characteristic of the larger group.

inbreeding

Answer 5

Sexual reproduction between two related individuals.

Question 6

adaptive potential

Answer 6

The ability for a population to adjust to new environmental selection pressures.

Question 7

interbreeding

Answer 7

When two individuals living in different populations mate and have offspring.

Question 8

gene flow

Answer 8
