What is the difference between phylum and genus

Generally phylum is referred in animal classification systems, whereas Division similar rank to phylum is found in plant and fungi classification instead of phylum. Class is generally known as the 4th highest taxonomical rank if we consider sub-phylum and super class the rank would be sixth in between phylum higher to class and order sometimes sub-class, infra class or super order. Ex — Class Insecta comprised of about 1.

Within Mustelidae , two lineages corresponding to skunks and otters are recognized, which have been assigned the names Mephitis and Lutra , respectively: names in capitalized italics indicate the genus category plural, genera. Particular forms of skunks and otters are Mephitis mephitis and Lutra lutra : this follows the invariant rules that genus and species names are always written in italics , the genus names is always capitalized , and the species name is always in lower-case.

After the first use in a scientific paper, and or where it will not be ambiguous, the genus name may be abbreviated, in this case as M. Within the family Canidae, the domestic dog and wolf lineages are recognized as related and are placed in the same genus, Canis , and abbreviated as C. Other taxonomic distinctions are possible. Because it is recognized that the weasel and dog families are more closely related to each other than either is to cats, the former pair may be placed in a single superfamily designated Canoidea.

Cats along with Hyenas will be placed in an alternative superfamily, Feloidea. Taxonomists who wish to emphasize the differences between these groups may designate them as different suborders : Caniformia and Feliformia. When writing the scientific name of an organism the name of the species is written as the second part. The species name is written in italics and lowercase letters. Genus is a taxonomic classification, which ranks below family and any Subfamily and above Species.

Whereas species is a taxonomic classification that ranks below Genus in the taxonomy hierarchy, but it is the fundamental level of classification for an organism. A genus is composed of many different species, whereas species are composed of different subspecies.

See the chart below which outlines how this hierarchy works. A genus consists of a large number of organisms, whereas species consists of a fewer number of organisms. Meaning all the different species of zebra, donkey, and horses all belong to Equss.

You can compare this to your name which consists of the first name and the surname. Organisms between separate genera can never produce offsprings that are fertile or capable of reproduction.

In contrast species and its subspecies can produce fertile offspring. Whereas organisms from separate species but under a specific one common genus may or may not be able to reproduce fertile offspring.
