What is a variety?

In biology, a variety is a taxonomic rank below that of subspecies and above that of form. It is used to classify populations of organisms that show certain distinctive characteristics that differentiate them from other populations of the same species. Varieties occur naturally due to genetic variations within a species and can arise from environmental differences, geographical isolation, or genetic mutations. Some common factors used to distinguish varieties include physical characteristics, behavior, adaptations, habitat preferences, or chemical differences. They play an important role in understanding the genetic diversity and ecological significance of different populations within a species and can provide valuable insights into evolutionary processes and the genetic structure of biological populations.
