How does a runner lead to asexual production in the strawberry?

I have to explain this, but am confused.

Any help much appreciated.
How does a runner lead to asexual production in the strawberry?
Asexual reproduction is creation of offspring where genetic material is not exchanged. The offspring are an identical copy of the parent. This happens often in plants. With a strawberry the runner is a shoot that comes off the plant and "plants itself" and turns into another plant. Therefore this second plant is offspring of the first but is an exact genetic copy of the parent plant.
Reply:A runner creates another plant. But there were no seeds involved. Seeds need to be fetilized, which involves sexual reproduction.

No seed, therefore it is asexual reproduction.
