Examine the cladogram; What is one shortcoming of this proposed family tree?

Answers

Although we do not have access to the diagram in question, we can say in general terms that cladograms are used to study the ancestral relationship of organisms based on physical traits and phenotypes.

Why is a cladogram not very effective?

The major shortcoming produced by a cladogram is its lack of genetic factors. Cladograms focus on comparing organisms based solely on phenotypes and physical traits, which results in errors due to ignorance of genetic factors which would allow for more precise results.

Therefore, we can confirm that cladograms are used to study the ancestral relationship of organisms based on physical traits and phenotypes, and their shortcoming is the lack of genetic factors.
