Our molecular tree has a length of 170 and our morphological tree has a length of 15. Which is preferred and why? a) Morphological. The traits used are more meaningful b) Molecular. There are more traits used and it is unambiguous. c) Morphological. It is more parsimonious d) Molecular. It is less parsimonious.

The option that will be preferred is B. Molecular. There are more traits used and it is unambiguous.

It should be noted that the tree that has the fewest evolutionary changes will be the most parsimonious tree. This is the method that's used in phylogenetic analysis for the construction of trees.

Since the molecular tree has a length of 170 and our morphological tree has a length of 15, then the molecular approach will be vital as there are more traits that are used and it is unambiguous. The approach is also more accurate.

The correct answer is - option B. Molecular. There are more traits used and it is unambiguous.

Explanation:

In this case, there is more than one trait is used, and for the phylogenetic analysis such a case, the molecular method is the best approach.

This method considers the origin of the species or phylogeny of particular species. The molecular approach is preferred for un-ambiguously and multiple traits are used in the molecular approach,

hey there!

so, when you eat, your teeth chew and grind food into smaller pieces. this is mechanical digestion. then reactions aided by digestive enzymes break down large food molecules into smaller molecules. this is chemical digestion. the two processes change the food into simpler substances that can be used by the body for raw materials and energy.

hope this
