two parts and thank you
Below is a phylogeny of the Brassicales from Schranz and Mitchell-Olds (2006). If I was interested in constructing a phylogeny showing the relationship between different species of plants in the genus Brassica, what taxa or taxon should I use to root the tree AND why? (4 pts.) 4) Arabidopsis brau Brassana bn Cleome spinosa Cleomel Cappuris Carica hen se important to determine (4 pts.) lecting morphological characters to be used in the construction of a phylogeny, it is and compare "similar" structures. What do we mean by "similar?"Explanation / Answer
According to the illustration shown in the information, the degree of relatedness of different species of the Brassica can be easily understood. Here, it is important to note that while constructing a phylogenetic tree, it remains highly important to critically observe the similarities and differences among different species so that a correct order of relatedness could be produced.
Here, the term 'similarities' represents the gross morphological, physical, physiological and anatomical features which are shared by these species. While conducting an even more close investigation for the similarities, genetic dispositions are also investigated to understand the degree of relatedness of different species.
Thus, more are the number of features shared by different species, more are the 'similarities' between them.
