A) in a population without this kind of variation, the species is doomed to extinction.
B) when all individuals have the same genes, then all individuals are exactly alike in all respects.

Final Answer : D, Explanation :  Darwinian natural selection relies on hereditary variation to drive evolutionary change. This variation allows for certain traits to be more advantageous in a given environment, and these traits are then more likely to be passed on to the next generation. Without hereditary differences, there would be no basis for some individuals to be more likely to survive and reproduce than others, thus halting the process of natural selection.
