Answer:
In the case of HIV-1, this loss-of-function mutation has proven to be beneficial.
Explanation:
Loss-of-function mutations are those that result in a gene product that has less or no function compared to the unmutated gene. When the allele completely loses function, (null allele), it is called an amorphous mutation. Phenotypes associated with these mutations are usually recessive, except when the organism is haploid, or when the reduced dosage of the normal gene is not sufficient to produce a normal phenotype (this phenomenon is called haploinsufficiency).
As mentioned earlier, this type of mutation results in a defective gene, but the text shown in the above question shows an example of a beneficial loss-of-function mutation because this mutation provides resistance to HIV-1 infection.

Answer:
Human trafficking is a huge epidemic all across the world. In america specifically there is a large population of human traficking in ohio, new york, new jersey, and florida. Girls who seem vulnerable are targetted by pimps or their head girl, who has been part of the traficking for so long that she feels attached to it (stocckholm syndrome). The girl will either be tricked into joinging as a means of escape or drugged and forced into sexual acts. The girls can often never get out. The pimp may let them leave if they can pay him some exorbinant amount of money, which they almos tnever can. Girls are more likely to die than be let go or escape. They are forceed into many sexual things with older perfeverted men the marjority of the time, and they usually see none of hte money they would be making. They are sometimes sold as slaves or sex dolls or even as an easy victim for serial killers
