  The Ultimate Molecular systematics Dog Breeds Information Guide and Reference
Molecular systematics is particularly important in, and compatible with, the cladistic approach to taxonomy; however the general cladistic approach is older than molecular systematics and does not necessarily depend upon it.
In a molecular systematic analysis, the haplotypes from a substantial sample of individuals of the target species or other taxon are determined for a defined area of genetic material.
Molecular systematics often uses the molecular clock assumption that quantitative similarity of genotype is a sufficient measure of the recency of genetic divergence.

Cladistics (Greek: clados = branch) is the most prominent of several methods of phylogenetic systematics (Greek: phyle = tribe, race and genetikos = relative to birth, from genesis = birth).
Phylogenetic systematics occupies itself by researching evolutionary relationships, by descent, of living things (see biology).
Computational systematics allows the use of these large data sets to construct objective phylogenies.

 Cladistics
Cladistics (or phylogenetic systematics) is a branch of biology that seeks to erect classification groups for all organisms, based solely on their evolutionary relationships.
Cladistics differs from phenetics, which groups organisms based on overall similarity (morphological approach), and from more traditional approaches based on "key characters".
As DNA sequencing has become easier, phylogenies are increasingly often constructed with the aid of molecular data.
