Specific Terms
BIOTYPE	A summary term for Carassius individuals with a certain ploidy level or reproduction mode (e.g., diploid, triploid, sexual, gynogenetic biotype). Based on sequencing data, it is possible to classify each biotype into separate mitochondrial taxa
COMPLEX	An evolutionary group of related taxa involving all possible biotypes, hybrids, non-specific genotypes assigned to them due to morphological and genetic similarities between each other
FORM	A low taxonomic unit within a species or biotype with unified morphological traits. Often varying in body colour, shape, fin length etc. (e.g., Carassius domesticated form, Carassius xantic form)
HOLOTYPE	A single physical example (or illustration) of an organism, known to have been used when the species (or lower-ranked taxon) was formally described. It is either the single such physical example or one of several such, but explicitly designated as the holotype
HYBRID SPECIES	Hybridization gives rise to novel allelic combinations that contribute to the spread and maintenance of stabilized hybrid lineages generally recognized as species. The process of hybrid species formation is a hybrid speciation
HYBRID	In the strict sense, a hybrid is the first offspring resulting from the reproduction of two or more distinct species. When hybrids mate with parental species the resulting offspring is called backcross
NEOTYPE	A specimen later selected to serve as the single type specimen when an original holotype has been lost or destroyed or where the original author never cited a specimen
SPECIES	A basic (basal) taxon of hierarchical systematic classification defined as a related group of organisms of the same history able to cross between each other (but usually they are not able to cross between another species)
TAXON	(in plural TAXA) A group of one or more populations of an organism or organisms which form a taxonomic unit
