Question

Cancer is a disease caused by mutations. Yet in most instances, if a parent tragically dies from cancer, this does not put their child at a greater risk than a person who parents don't develop cancer. How can cancer be caused by mutations and ot be heritable?
a. most cancers arise from mutation in germ line cells
b. mutations that cause cancer occur on specific cells, such as sex cells
c. mutations caused by environmental agents, such as tobacco smoke, occur in somatic cells
d. mutations that cause cancer are specific and cannot be passed on regardless of the type of cell they occur in
​

Answer 1

Answer:

c. mutations caused by environmental agents, such as tobacco smoke, occur in somatic cells

Explanation:

just because you're parents smoked and got lung cancer doesn't mean you'll get lung cancer. (unless you're breathing the smoke, but that's different from inheriting it.)
