Question

Mutated DNA in somatic cells occurs frequently but this modified DNA cannot be passed along to offspring because —
A
modified DNA in somatic cells is recessive
B
offspring typically reject modified DNA
C
only gamete cells carry genetic material to offspring
D
offspring mutations happen only when somatic cells are diseased

Answer 1

C

Only mutations in germ cells (sperm or eggs) can be transmitted to offspring. Somatic-cell mutations affect only the individual’s body cells and are not incorporated into gametes, so they are not inherited. Options A, B, and D are incorrect for the reasons above.
