Question

Phylogenetic trees constructed from evidence from molecular systematics are based on similarities in _____.

Answer 1

Answer:

mutations to homologous genetic loci

Explanation:

Phylogenetic tree, which is a diagrammatic representation of evolutionary relationship among organisms, can be constructed from evidence from molecular systematic with regard to the similarities in the mutations to homologous genes.

Homologous genes are genes that are inherited by two species from a common ancestor having similar DNA sequence. An example of homologous gene is Orthologous gene, which is said to have be brought about by speciation.
