To arrange the events in the correct sequential order for an artificial hybridization program, we can follow these steps: 1. **Selection of Parents (b)**: The first step in the artificial hybridization process is to select the desired parent plants. This involves choosing the male and female plants that have the traits you want to combine. 2. **Emasculation (e)**: After selecting the parents, the next step is to emasculate the female parent. Emasculation involves removing the anthers (the male part of the flower) from the female flower to prevent self-pollination. 3. **Bagging (c)**: Once emasculation is complete, the stigma of the emasculated flower is covered with a bag (usually a paper or cloth bag) to protect it from unwanted pollen and to ensure that only the desired pollen is used for fertilization. ...
