The relationship between species and subspecies, the difference between subspecies and variants

Brief introduction. Subspecific intraspecific taxa refer to groups of organisms within the same species that are clearly different in morphological characteristics and traits due to regional, ecological, or seasonal isolation. For this reason, as an independent species, it must have 1 or 2 morphological characteristics that distinguish it from the original subspecies, that is, the location of the jade bud, the morphological characteristics and its composition, as well as the number, shape, and color of the tepals of the single flower, the number, shape, and color of the stamens, the number, shape, and color of the isolated single pistil, the number, shape, and color of the aggregated fruits, and the number, shape, and color of the fruits.

Secondly, the shape, color, and coat of the branches and leaves are also important classification criteria [1].

Detailed. Subspecies, a species classification class secondary to species, is the lowest taxonomic class recognized by the International Code of Animal Nomenclature.

Different subspecies of the same species can mate with each other to reproduce and have fertile offspring. For example: North American gray wolf.

and domestic dogs. But the yellow race and the white race are only a cultural concept, not a biological subspecies.

Populations with obvious geographical distribution boundaries and certain differences in morphological characteristics from other populations within the same species.

Subspecies develop into new species due to further geographic isolation leading to reproductive isolation.

In paleontology, the same population that is different from other populations in terms of internal morphological characteristics due to the difference in age distribution is also called a subspecies, which is a chronological subspecies. Therefore, subspecies can be divided into geographic subspecies and chronological subspecies. The subspecies name is one of three. [2]

Biological groups that occupy different geographical distribution areas or hosts, do not overlap with each other, have imperfect reproductive isolation and have certain morphological differences. This trait is highly heritable.

Setting standards. Taxonomists always define a species first, and then a subspecies.

It must be noted that once a subspecies is established, there are at least two, and if there is only one subspecies, then there is no need for this subspecies. Once the subspecies has been defined, it is necessary to classify all the groups that have been found in the species into their own distinct subspecies, and there will be no such thing as a normal species and a few subspecies that are a lower subspecies.

Criteria for division. Two populations with exotic distributions within a species are taxonomically different from each other, and the individuals differ from each other in at least 75% of the population, i.e., 75% of the individuals in population A are different from all individuals in population B, and the two populations are considered to be different subspecies [2] .

The unit of a subspecies is smaller than that of a species, and it is a class-level taxonomic class next to a species. For example, the Siberian tiger and the South China tiger both belong to the tiger species, but they belong to different subspecies, and different subspecies of the same species can mate and reproduce and have offspring.

Subspecies: It is generally considered to be a group within a species, with some variation in morphology, and geographical, ecological or seasonal isolation, such a group is a subspecies. It belongs to two subspecies within the same species and is not distributed in the same geographical distribution area.

Variant: A species that has some variation in morphology, and the variation is relatively stable, its range (or area) is much smaller than that of subspecies, and it has a common distribution area with other varieties within the species.

1.Different subspecies of the same species can mate with each other to reproduce and have fertile offspring. An important basis for judgment is that "reproductive isolation is imperfect", and offspring can be reproduced between subspecies.

2.It has obvious geographical distribution boundaries and certain differences in morphological characteristics from other populations within the same species. That is, the distinguishing conditions of subspecies, there is a certain geographical isolation, and there are certain morphological differences.

A subspecies is a taxonomic unit of taxonomic subspecies. It is a group within a species, but there are differences in some morphological or physiological characteristics, gene frequency, chromosome structure, etc., and there are different geographical distributions. Individuals of different subspecies can mate with each other.

Produce offspring of childbearing potential.

Breeds, on the other hand, refer to the classification of the same species, sometimes similar to the subspecies explanation (when referring specifically to sub-species).
