vegetative reproduction is taking an existing plant and cloning it by cutting of a pence and letting it grow into a full plant.

For example take a cutting from a Forsythia plant and put it into moist soil and it will root. since there is only one plant involved and no cross pollination then the result is exactly the same as the parent plant.

If you put a sweet potato in water and let it sprout and then cut these many sprouts off and plant them they will all be genetically identical -- there was only 1 source plant and not cross pollination.

Nurserymen use cutting and other vegetative methods to keep the crop exactly the same as the parent-- they want its traits and do want to risk the variation that seed allow due to cross pollination.
