Question

1 Section: TA: 1a. What are the taxonomic classifications (kingdom - species) for broccoli and cauliflower? Use the following link to find the taxonomic information: http://www.ncbi.nlm.nih.gov/ Choose "Taxonomy" in the "All Databases" dropdown box. (2 marks) 1b. What is seen in the question la results, and what process is responsible for these results? (2 marks) 2. Use your tutorial section's PTC and Broccoli bitterness scores to create a scatter plot. The data will be posted in your tutorial's discussion forum after your scheduled tutorial. (4 marks) 3. Calculate and report the correlation coefficient for the data that was used in question 2. What strength of correlation is present in the data? (2 marks) Tutorial 4: Data collection and analy Total: /18

Answer 1

Braccoli:
Kingdom = Plantae
Clade = Tracheophytes
Clade = Angiosperms
Clade = Eudicots
Clade = Rosids
Order = Brassicales
Family = Brassicaceae
Genus = Brassica
Species = B. oleracea
Cultivar group = Italica group

Cauliflower:
Kingdom = Plantae
Clade = Tracheophytes
Clade = Angiosperms
Clade = Eudicots
Clade = Rosids
Order = Brassicales
Family = Brassicaceae
Genus = Brassica
Species = B. oleracea
Cultivar group = Botrytis Group

Both of them belong to the same species. However, they belong to different cultivars (Similar to different strains)
This is due to artificial selection (or natural selection at specific eco-localities) for specific traits
