Imagine that an accident has exposed you to a mutagen. however, the medical report indicates that only your germ cells (not your somatic cells) have been affected by the exposure. speculate on how this might or might not change your future.

Generally, we can say that we have to kind of cells based on reproduction:
Somatic and germinal cells.
Germ cells come from a division of stem cells (meiosis). They are at the origin of the formation of the reproductive cells, or gametes (spermatozoids in the man and the oocytes at the woman) The DNA of these cells affected by mutations can be transmitted to the offspring (which is not the case for somatic cell mutations).

Somatic cells represent all the cells of the body, except germ cells and embryonic cells. It could be bone cells, liver cells or blood cells... Theoretically, since these cells are not germ cells, they will never transmit to their descendants the mutations they may have undergone. But it could lead to cancers if they are mutated (skin, liver, or lung cancer).
