Phylogenetic trees can be based on a phenotypic variation b

Phylogenetic trees can be based on;

a. phenotypic variation

b. ecological requirements

c. molecular variation

d. reproductive isolation

e. all of the above

Solution

Correct answer is e. All of the above

Phylogenetic tree is made on the bais of common ancesstors sharing an the genetic diversity. This will lead to variation in phenotype according to the ancesstor and at the same time molecular variation will occur.

according to the genetic variation ecological requirement and reproductive isolation will occur.

All of these are interrelated according to sharing of common ancesstor.
