Which of the following is an example of a beneficial mutation? a mutation causing uncontrolled cell division in human tissue cells a mutation inhibiting human immunodeficiency virus from entering the host cell a mutation resulting in partial or complete loss of chlorophyll pigments in plants a mutation resulting in a squirrel being born without ovaries

A mutation causing uncontrolled cell division in human tissue cells is cancer and definitely not beneficial.
A mutation resulting in partial or complete loss of chlorophyll pigments in plants will lead to a plant not being able to photosynthesise and therefore unable to respire leading to death.
A mutation resulting in a squirrel being born without ovaries means the squirrel will be unable to reproduce and there for is not beneficial.
The answer is therefore a mutation inhibiting human immunodeficiency virus from entering the host cell. This means that the person who has this gene is unable to contract HIV which is beneficial
