Question 103

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

  1. Only if the cell is one that produces gametesBonne réponse
  2. Only if the mutation is a beneficial one
  3. If the cell is any cell in the animal's body
  4. Only if the same mutation occurs in both parents

Explication

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.
