Answer 1

Answer:

What are some examples of positive mutations?

These beneficial mutations include things like lactose tolerance, rich color vision and, in some, a resistance to HIV. Beneficial mutations can confer an advantage to the organism possessing them and, over time, these mutations can spread throughout a population.

Mutations have occurred in bacteria that allow the bacteria to survive in the presence of antibiotic drugs, leading to the evolution of antibiotic-resistant strains of bacteria.
