The correct answer is Panda and Wolf.
These two species are showing the greatest amount of genetic diversity. Genetic diversity refers to the total number of genetic features in the genetic makeup of an organism. It is differentiated from genetic variability that illustrates the capacity of genetic features to change.
The genetic diversity functions as a way for populations to amend with the changing environments. Genetic variation is beneficial for a population as it allows some of the species to adapt to the environment while sustaining the existence of the population.
