Brassica

2 November Brassica Oxford was the first to approve the fingerprinting orDNA profiling in 1984. Since then, people all over the world have become aware of the fact that each of them has a unique structure of the deoxyribonucleic acid (DNA) (Steel KMMRB, 2004). This powerful discovery provides doctors with an objective means of identifying people. DNA of different animals, plants as well as humans has been frequently studied in the past few decades in different fields that include but are not limited to the molecular archaeology, identification of genetic diseases, and investigations pertinent to the forensic science paternity (WUMPAAY, 2007). AFLP is the method which is employed for the DNA fingerprint. AFLP makes use if selective PCR in order to make the restriction fragments drawn from the whole genomic DNA more intense (Vos P, 1995).
Figure 2 relates the broccoli, turnip and pak choi to the Brassica genus. In addition to that, the pak choi and turnip form the same subgroup because of their relation to the Brassica rapa. Since Radish belongs to Raphanus, that is a totally different genys, it forms a separate group. This finding was consistent with its use as an outgroup control. Outgroup plays the role of a reference group that helps identify the altering link between the various groups of interest and itself. This enhances the efficiency of the phylogenetic analysis software in assessing the dendrogram which is the phylogenetic tree. It also enhances the functioning of the program by separately dealing with the group of interest and the outgroup.
