Question

These sources of information are used to determine the relationships among different species. Which provides information at the species level?
A) comparison of fossil records
B) comparison of the nucleotide sequences in DNA
C) comparison of the morphology of the different species

Answer 1

DNA bar coding and macroevolution research provide much information at the specie level so the
 comparison of the nucleotide sequences in DNA
 provides information at the species level
because specie is directly related to gene
so option B is correct
hope it helps
