Which of the following types of mutations are thought to be least common? A) somatic mutations B) germ-line mutations C) neutral mutations D) Harmful mutations E) beneficial mutations

Solution

Beneficial mutations

Explanation

Although mutations that cause changes in protein sequences can be harmful to an organism, on occasions the effect may be positive in a given environment. In this case, the mutation may enable the mutant organism to withstand particular environmental stresses better than wild-type organisms or reproduce more quickly. In these cases, a mutation will tend to become more common in a population through natural selection

all other mutation like somatic, germline, neutral and harmful mutations are common
