Variations in populations

California condors are large, North American vultures that nearly went extinct in the 1980s as a result of habitat destruction. Through captive breeding and reintroduction of populations into the wild, the number of wild California condors is slowly increasing. However, because of the population bottleneck, all of the condor populations that currently exist in the wild are descended from a breeding population of just 14 individuals.

Which two claims are best supported by the information provided above?

👁️ Note that there are 2 answers to this question.

(Choice A)
Wild California condor populations have little genetic diversity and are therefore at risk of decline.
(Choice B)
Because of the bottleneck, the wild California condor populations are more resilient, containing individuals whose genes were selected for by natural selection.
(Choice C)
Wild California condor populations can better withstand disruptions to their habitats than they could before the population bottleneck.
(Choice D)
Because of the bottleneck, the wild California condor populations are less likely to contain individuals that can withstand a certain environmental change.
