In self- pollination, there is no diversity in the genes and therefore the purity of the race is maintained.

In the case of cross-pollinating plants, there is a threat of the entire crop dying out if there are no pollinators to facilitate the process. The disadvantage of self-pollinating flowers and plants is that there is little genetic diversity because the same genes are passed down from the parent plant to the offspring.
