Answer 2

The disadvantages of self pollination are_

(1) Continued self- pollination, generation after generation, may lead to weakening of the variety or the species. The seeds produced through it re poor in quality and give rise to less vigorous offspring.

(2) The weaker or defective character of the variety or breed cannot be eliminated.

(3) It does not yield new varieties. The genetic traits of the same plant with no change and without any intermixing are passed on to the next generation. There is little chance for improvement in the next generation.
