Abstract
Brassica rapa is a small flowering plant that is often used in classroom experiments due to its small size, low-maintenance growing conditions, and quick life cycle. Several mutant lines have been bred and briefly described, although not much is known about the actual genetic changes and therefore all the downstream effects of that mutation. Nine different mutant lines of Brassica rapa were grown to more carefully identify the phenotypes affected by the mutations. Tall plants were grown over 4 weeks and height and leaf size were measured. There is a significant difference between both the height and leaf size of the Tall variant plants and Wild Type Brassica rapa. This supports the hypothesis that Tall variant plants will have an increase of height. However, it was hypothesized that the Tall Variant plants would have larger leaves when instead the presence of the Tall Variant mutant leads to a decrease in leaf length (cm.)
