Answer to Question 1
Cultivar identification is important to establish ownership. Cultivars can be
distinguished by the flower, fruit, and vegetative parts. In addition, chemical taxonomy

fingerprints. Another method is molecular evidence using the Polymerase Chain
Reaction (PCR) for DNA analysis.
