Abstract
The experiment that was being completed was the genetics of plants using Fast Plants. The purpose of this project was to understand Mendel’s concept of a Dihybrid by performing similar crosses and calculated the phenotypes that are displayed. This project was conducted over many weeks by planting F1 seed and waiting for them to grow then cross-pollinating the F1 plants to produce the F2 seeds. Next students were to plant the F2 seeds and record the phenotypes. After all the data was collected we ran a statistical test called a Chi Squared to see if the hypothesis put foreword was correct. After running the Chi Squared Test the Group and Class hypothesis was accepted. So in conclusion the fast plants resemble Mendel’s genetic experiments. …show more content…
Each group labeled the quad they planted as F1. Our Professor had the Parental Fast Plants on the counter so everyone could see the phenotypes. The phenotypes of the Parental were non-purple stem, green leaf and purple stem, green leaf. Over the next week we observed our F1 Fast Plant and recoded the phenotypes. The third week is when we started pollinating the flowers. We used a bee stick to cross-pollinate the flowers. The reason we use a bee stick to pollinate is that fast plants do not self-pollinate, so bee sticks are used to successfully reproduce. Over the next week we had to pollinate the flowers two more times so the flowers could achieve maximum fertilization. In the following week we had to complete the pollination and pinch off any unopened flower buds. Then from weeks 5-7 we monitored the seed formation. And on week 7 we took the fast plants off their watering system and let them dry for five days. Then in week 8 we collected our F2 seeds and planted them in a quad. Then lastly in week 9 we observed our F2
