Answer :
The two things that are compared when patterns of evolutionary relationships are constructed using molecular phylogenetics are the sequences of nucleic acids and amino acids.
What do you mean by Phylogenetics?
Phylogenetics may be defined as the branching patterns made to represent the evolutionary history or relationship between different species, organisms, or characteristics of an organism.
Nucleic acids are the building blocks of genetic material i.e. either DNA or RNA. While amino acids are the monomers of proteins. Both these two things are required to compare the similarity or dissimilarity between two or more organisms.
Therefore, the two things that are compared when patterns of evolutionary relationships are constructed using molecular phylogenetics are the sequences of nucleic acids and amino acids.
