Question

Some humans have genes that make them resistant to infection by HIV. Would human populations likely evolve differently in areas of the world where HIV infection rates are high? Explain your logic.

Answer 1

Answer:

Evolution changes the species characteristics with the change in the passage of time. The mutation, natural selection and genetic drift can bring changes in the species.

AIDS is caused by the HIV virus that affects the human population. Some humans has the are resistant to HIV virus. The areas that has high infection HIV rate, the human population is likely to evolve in this area. The traits that are responsible for the resistance of the HIV traits gets increase with the passage of time.

Answer 2

Answer:

Yes, the population can evolve in different areas.

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.
