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. Non-purple hairless plants were grown over 4 weeks and the height and number of trichomes were measured. Our hypothesis stated that the lack of anthocyanin would cause the non-purple hairless to be weaker than the wild type. It is concluded that even though the non-purple hairless is shorter in height, there is not a significant difference to support the idea that the non-purple hairless is weaker. The wild type did have trichomes, while the non-purple hairless were indeed hairless.
