Can Somatic cell mutation can be transmitted to the offspring?

No - it cannot. Somatic cells are not involved in reproduction. For a mutation to be passed on to offspring, it must occur in sex cells.

No. Mutations would have to affect the germ-line cells to be passed on to offspring.

A mutation in a non-germline cell (germline cells are sperm, egg, etc.).

its not.

DNA mutations can pass from parents to off spring only if the mutation occurs in the sex cells (eggs and sperm).
