Question 20
20.
The drawing shows a potato plant producing new tubers (potatoes). Buds on the stem of the parent plant produce stolons. The new tubers are formed at the ends of the stolons (stems that grow downwards).
(a) Explain why the new tubers are genetically identical to each other.
Question 21

Which is the best description of asexual reproduction?
A process producing identical offspring from only 1 parent
A process producing genetically identical offspring (clones)
A process producing genetically identical offspring (clones) from only 1 parent.
Which is an advantage of asexual reproduction?
Produces offspring well adapted to current environment
Produces variation which allows natural selection to occur
Prevents the entire population being wiped out by the same disease
Which is a disadvantage of asexual reproduction?
If the environment changes there is no genetic variation for natural selection to act on
If the environment changes the whole population will die
