Question

In cladistics

• A. Data for cladogram is presented
• B. Derived characters help to construct cladograms
• C. A clade must contain the common ancestor plus all its descendants
• D. All of the above

Answer 1

Answer: (D)

• A clade is a grouping that includes a common ancestor and all the descendants of that ancestor. A key feature of a clade is that a common ancestor and all its descendants are part of the clade.
• Cladograms emphasize the sequence or order in which derived characters arise from the central phylogenetic tree and thus data for cladograms is present in the cladistics.
  
• Cladistics is now the most commonly used methods to classify organisms.

So the correct option is All of the above.
