How do germ-line mutations differ from somatic mutations? (a) Germ-line mutation

Question

How do germ-line mutations differ from somatic mutations?

(a) Germ-line mutations involve small changes to DNA such as base-pair substitutions, while somatic mutations usually involve large deletions.

(b) Germ-line mutations occur during DNA replication, while somatic mutations do not.

(c) Germ-line mutations result in mutant gametes, while somatic mutations do not.

(d) Germ-line mutations are reversible, while somatic mutations are not.

(e) Germ-line mutations result in cancers, while somatic mutations do not.

Explanation / Answer

Option C is correct. Germ line mutations results in mutant gametes, while somatic mutations do not.

All other options are inappropriate, Both involves small chages to DNA, both occur during DNA replication, both are reversible and both can result in cancers. But only germ line mutation results in mutant gametes, while somatic mutations do not.
