A mutation occurs in a cell of an adult animal. Under what condition can it be passed to that animal's offspring?

Only if the cell is one that produces gametesՃիշտ պատասխան
Only if the mutation is a beneficial one
If the cell is any cell in the animal's body
Only if the same mutation occurs in both parents

Բացատրություն

Offspring are formed from gametes, so only a change present in the DNA of a gamete can travel to the next generation. A change in a skin cell or a liver cell is copied into that cell's descendants inside the same body and goes no further than that body.
