Cold - resistant plants allow crops to be grown in new areas. Whats another word for cross-pollination? Chances are high that desirable qualities may get eliminated and unwanted characteristics may get added due to recombination of genes. Cross pollination is important because it helps to keep the genetic diversity of our food crops. This process is carried out by various pollinating external agents. For example. Disadvantages of self-pollination: (1) Continued self pollination, generation after generation, may lead to weakening of the variety or the species. A large number of pollen grains are required for pollination. 2. The yield by such seeds is very high and never falls below an average minimum. In this way, there is less wastage of residue. 2. Disadvantages of cross-pollination. A disadvantage is that plants have to depend on an. The ability of some plants to self-fertilize has its advantages, especially in areas where there aren't many pollinating insects.
