In self- pollination, there is no diversity in the genes and therefore the purity of the race is maintained. The plants do not depend on external factors for pollination and even smaller quantities of pollen grains produce have a good success rate in getting pollinated.
disadvantages of self-pollination are as follows: May lead to the weakening of variety or the species due to continued self-pollination, thereby affecting the quality of offspring. ... Self-pollination does not yield new varieties, hence fewer chances of improvement in the subsequent generation.
