Only changes in cells can be passed by offspring?

Only changes in germ cells, which are the reproductive cells (sperm and eggs), can be passed on to offspring. Somatic cell changes, occurring in non-reproductive cells, do not affect the genetic material transmitted to the next generation. Therefore, while mutations or adaptations in somatic cells may impact an individual's health or traits, they are not inherited by offspring. In contrast, germline mutations can lead to hereditary traits in subsequent generations.
