From about, fish species estimated to occur, the basic karyotype characteristics, i.e., diploid chromosome number (2n) and the number of chromosome arms (NF), are known for not more than 3, fish species, which represents only about% of the total number Lack of introns: Making amplification straightforward. Lack of introns: Making amplification straightforward. Nuclear genes are often interrupted by introns, making amplification difficult or unpredictable. Thus species are grouped within genera, genera are grouped within families, families are grouped within orders, and so on (Figure 8) From about, fish species estimated to occur, the basic karyotype characteristics, i.e., diploid chromosome Tools of a TaxonomistLaboratory Oriented Morphological Evidence Anatomical Evidence Palynological Evidence Embryological Evidence Cytological Evidence Originally as Enterprise Vocabulary Net (), stand-alone vocabulary management tool (replacing Enterprise Vocabulary Net) or module of TopBraid Enterprise Data the digitisation of taxonomic literature to address the taxonomic impediment the shortage of taxonomists and taxonomic tools that hinders work in other areas of biodiversity Introduction to Modern Taxonomic Tools: Karyotaxonomy.
