Which of the following is considered the closest relative to HIV-1? Chimp SIV Baboon SIV Green monkey SIV Polio HIV-2 Hooper hypothesized that HIV-1 first entered humans in which decade? 1920s 1930s 1940s 1950s 1960s In Exercise 1 (Molecular Evolution), how would you describe the change in variation of the virus population after 1000 generations? There is more variation after 1000 generations. There is less variation after 1000 generations Amount of variation is about the same after 1000 generations.

Solution

1. It is chimp SIV as HIV -1 is related to viruses found in chimpanzees and gorilllas.

2. According to hooper hypotheses it is around 1960\'s that HIV-1 entered humans.

3.according to the evolution of virus two third of the viruses are repeated in long terms so the amount of variation is about the same after 1000 generations.
