Question

differen between monotypic species and polytypic species

Answer 1

What Is A Monotypic Species?

When a species is designated as monotypic, it means that none of the organisms within the classification are divided into subspecies. Typically, members of a monotypic species classification live within close proximity to one another and share high degrees of biological similarity. Because no real distinction can be made among the population members, it is considered monotypic. Any difference among monotypic species is largely considered irrelevant and believed to occur at random, rather than as the result of genetic factors.
One example of a monotypic species is the Hyacinth macaw which inhabits some areas of South America. This bird is distributed in 3 primary habitats: the Amazon Basin of Brazil, the Pantanal region between Brazil and Bolivia, and the Cerrado region of Brazil. The Hyacinth macaw belongs to the Anodorhynchus genus and hyacinthinusspecies. As a monotypic species, the Hyacinth Macaw is the only organism within the species classification. It is a large blue bird with yellow skin around its lower beak and eyes.

What Is A Polytypic Species?

When a species is designated as polytypic, it means that all the members of the classification can be further divided into a minimum of two subspecies. Each subspecies designation typically refers to a very specific population of organisms that can only be found in one particular habitat. That habitat is not shared with other subspecies of the same species classification. Because these distinct populations are located at a significant distance from each other, often isolated by large bodies of water or mountains, the subspecies of a polytypic species tend not to reproduce together. Biologists are clear to point out, however, that subspecies are biologically capable of producing fertile offspring. In fact, many subspecies have been known to procreate when in close proximity to each other.
