Text Solution

Verified by Experts

The correct Answer is:
A
Species with low genetic variability are generally at significantly greater risk of extinction than the species with more genetic variability, simply because they have a more limited arsenal with which to respond to the varieties of environmental change. Species with extremely low genetic variability are particularly vulnerable towards a new disease, predator or other environmental challenges, e.g., lack of genetic variability in the African cheetah (Acinonys jubatus) has been considered to be a significant factor contributing towards decline of cheetah population.
