defon

Answer:

The correct answer is "mutations to homologous genes".

Explanation:

The missing options of this question are:

A) morphology.

B) the pattern of embryological development.

C) biochemical pathways.

D) habitat and lifestyle choices.

E) mutations to homologous genes.

The correct answer is option E) "mutations to homologous genes".

Modern cladograms do not use physical characteristics to establish evolutionary similarities among species. Modern cladograms are constructed from evidence from molecular systematics based on similarities in mutations to homologous genes. The more similar are the homologous genes, the less different their genetic sequences are, and are considered more closely related in their evolutionary tree.
