Answer:
Yes, the population can evolve in different areas.
Step-by-step explanation:
In the given question, a condition is given in which some individuals have the genes which provide resistant to HIV while most do not have.
There are chances that in the HIV infected regions the gene providing resistant to the HIV is passed on to the generation to form the resistant population against HIV whereas, in low HIV infected region, the gene remains suppressed. A similar condition was observed in the case of the development of sickle cell anaemia.
Therefore two population can evolve independently in a different population of the world.
