The system of classification based on evolutionary and genetic relationships among organisms, ignoring the morphological similarities or differences, is called
(a) cladistics
(b) phenetics
(c) classical systematics
(d) new systematics
(a) cladistics
Explanation:
“Cladogram” emphasizes that the diagram represents a hypothesis about the actual evolutionary relationships of a group. This history is deduced on the basis of certain shares like homologous characters. that are thought to indicate common ancestry. While “phylogenies” represent true evolutionary history. To other biologists, “cladogram” suggests that the lengths of the branches in the diagram are arbitrary, while in a “phylogeny,” the branch lengths indicate the amount of character change.
