Phylogenetic trees constructed from evidence from molecular systematics are based on similarities in ________.
A) morphology
B) the pattern of embryological development
C) biochemical pathways
D) mutations to homologous genes

Question

Quizplus · Accepted Answer

Phylogenetic trees constructed from molecular systematics are based on similarities in mutations to homologous genes. This is because molecular systematics involves the analysis of DNA and protein sequences, which are directly affected by mutations. Morphology and embryological development can also provide evidence for evolutionary relationships, but molecular systematics is more objective and accurate in determining genetic relatedness. Biochemical pathways may also reflect evolutionary relationships, but they are not as commonly used as molecular sequence data.
