Why can germ-line mutations be especially dangerous?

Germ-line mutations can be especially dangerous because they occur in the reproductive cells and can be passed on to future generations, potentially affecting an entire lineage. These mutations can lead to inherited disorders and increase the risk of diseases, such as cancer, in offspring. Additionally, since germ-line mutations can affect multiple systems in the body, their impact may be more widespread than somatic mutations, which are limited to the individual where they occur.
