Phylogeny and interrelationship found between various taxa on the basis of number, type and arrangement of chromosomes is
Phylogeny is the study of the evolutionary history of an organism, species or a group and the relationships they share with one other on an evolutionary basis.
In Karyotaxonomy, organisms are classified based on the chromosomal characteristics which also includes its number and arrangement.
In Cytotaxonomy, organisms are classified based on information provided by comparative cytological studies.
In Chemotaxonomy, organisms are classified based on the characteristics of various chemical constituents of organisms like proteins, DNA sequences, etc.
In cladistic taxonomy, organisms are classified according to common phylogeny or origin from a common ancestor.
