Question

select all that apply
select all of the following events that could lead to a population bottleneck.
□ colonization of an island by a small number of individuals
□ an infectious disease that kills a large proportion of the population
□ human destruction of a populations habitat
□ reduction in migration between two neighboring populations
□ a natural disaster such as an earthquake or flood

Explanation:

A population bottleneck occurs when a population's size is suddenly reduced. Colonization by a small number of individuals is a founder - effect related event. An infectious disease killing many, habitat destruction by humans, and natural disasters can all severely reduce population size. Reduction in migration does not directly cause a sudden reduction in population size like the others.

Answer:

• Colonization of an island by a small number of individuals
• An infectious disease that kills a large proportion of the population
• Human destruction of a population's habitat
• A natural disaster such as an earthquake or flood
