Answer :

The mutation in a fruit fly that can be passed on to its offspring is a mutation in the germline cells. These cells are responsible for producing eggs or sperm, which carry genetic information that can be passed on to the next generation. When a mutation occurs in a germline cell, it can be inherited by the offspring.

On the other hand, a mutation in a somatic cell, like a mutation in a cell of an eye, will not be passed on to the offspring. Somatic cells make up the body of the organism but do not give rise to eggs or sperm. Therefore, mutations in somatic cells are not inherited by the next generation.

In summary, mutations in germline cells can be passed on to offspring, while mutations in somatic cells, such as those in an eye cell, are not passed on to the next generation.
