Question

scientists hypothesize that modern cheetahs have experienced two genetic bottlenecks. scientists estimate the first occurred during the last ice age and the second occurred during a time of rapid agricultural growth in cheetah habitats. the graph shows the population size before and after the first bottleneck event occurred and just before the second bottleneck event.

part a
click on the blank box and select a word that describes the relative genetic diversity in the cheetah population before bottleneck event 1.
then, click on the blank box and select a word that describes the relative genetic diversity in the cheetah population after bottleneck event 1.

• there may be more than one correct answer.

select all that would apply. there may be more than 1 possible answer for each letter.

a = high
a = medium
a = low
b = high
b = medium
b = low

Explanation:

A genetic bottleneck reduces genetic diversity. Before the first bottleneck event, the population was large, so genetic diversity (A) was high. After the first bottleneck event, the population size decreased significantly, leading to a reduction in genetic diversity (B).

Answer:

A = High, B = Low
