Question

What are the basis of classification of animal breeds?

Answer 1

Aniaml species would be better. They are classified as:

Mammals - the ones with hairs and lungs, they breathe air.

Birds - with feathers and wings.

Fishes - with fins and scales. An important difference between a shark and a whale is that a shark has a vertical tail while mammals such as whales have horizontal ones. Fishes have gills, they cannot breathe air. Mammals can breate only in air.

Reptiles - cold blood, scales and soft eggs.

Then there are vertebrates and invertebrates. Scientists look for specific features while classifying them.

Answer 2

A breed is a variety of domestic animal that has been selectively bred by humans for certain characteristics - for example, German Shepherd and Rottweiler are breeds of dog, and Shire and Arab are breeds of horse. All breeds of a certain animal are the same species - there is only one species of domestic dog, to which all breeds belong, so whether it is a German Shepherd, Poodle or Chihuahua, it is still the same species. Therefore, different breeds do not have different taxonomic classifications.

Answer 3

first thing i would like to answer you is that there are first two kind of cells they are prokaryotes and eukarayotes after which there are two main kingdoms called plant and animal kingdom akay followed by which ther are many micro organisms which are present in both the kingdoms to be known then the next level since you have asked about the classification of animals i would say they can be divided into many groups such as athrapods nematods mollusc and arachnida which are termed as invertebrates as they do not have any body structure at all but whereas the humans birds reptiles fishes amphibians all have a fixed structure as well as they have a vertebral region which gives them the name

Answer 4

Mammals: Vertebrate animals characterized by the presence of sweat glands, including sweat glands modified for milk production, hair, and three middle ear bones used in hearing.

Birds: Birds are bipedal, endothermic (warm-blooded), vertebrate animals. Modern birds are characterised by feathers, a beak with no teeth, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a lightweight but strong skeleton.



Fish: The term "fish" is most precisely used to describe any non-tetrapod chordate, (i.e., an animal with a backbone), that has gills throughout life and has limbs, if any, in the shape of fins. Unlike groupings such as birds or mammals, fish are not a single clade but a paraphyletic collection of taxa, including hagfishes, lampreys, sharks and rays, ray-finned fishes, coelacanths, and lungfishes.

Reptiles: Air-breathing, cold-blooded vertebrates that have skin covered in scales as opposed to hair or feathers. They are tetrapods (having or having descended from vertebrates with four limbs) and amniotes, whose embryos are surrounded by an amniotic membrane.

Amphibians: Cold-blooded animals that metamorphose from a juvenile, water-breathing form to an adult, air-breathing form. Typically, amphibians have four limbs. Amphibians lay eggs in water. Amphibians are superficially similar to reptiles.

Arthropods: Characterized by the possession of a segmented body with appendages on at least one segment. They have a dorsal heart and a ventral nervous system. All arthropods are covered by a hard exoskeleton. Arthropods grow by shedding this covering in what are termed molts.
