Both of the above

None of the above

c

Both of the above

None of the above

Explanation / Answer

Answer:C

Phylogenetic tree which is also called evolutionary tree, shows the evolutionary relationship between the biological species. These relationships are based on morphological and genetical characteristics.These characteristics may be similar or different. Phylogenetic tree helps us to propose the hypothesis to understand the evolution of any species based on their traits and how these traits are developed.
