Question #46922
The Question
While in-situ conservation in Sacred Groves allows for dynamic evolutionary processes, shifting a critically endangered plant species entirely to an ex-situ facility (like a Botanical Garden) carries specific genetic risks. All of the following are valid biological concerns regarding this ex-situ transition, EXCEPT:
Options
- A.
The surviving population may experience a genetic bottleneck due to a limited founder size.
- B.
The loss of natural ecological selection pressures reduces the population's long-term adaptive potential.
- C.
The species undergoes complete morphological and genetic stasis, functioning identically to a Herbarium specimen.
- D.
Inbreeding depression may increase, leading to a significant loss of heterozygosity over successive generations.

Why This Question Is Tricky
Common Mistakes
Conceptual Pivot: Distinguishing between the genetic consequences of living ex-situ conservation (Botanical Gardens) and dead taxonomic aids (Herbaria).
Students often confuse the 'loss of adaptive potential' in ex-situ conservation with 'complete stasis'.
While ex-situ populations suffer from genetic bottlenecks and reduced heterozygosity, they are still biologically active and reproducing, unlike the completely static, dead specimens preserved in a Herbarium.
