Hint: They are the taxonomy, which makes use of the characteristics of cellular structures, like somatic chromosomes to classify organisms. They also provide considerable information on relationships.

Complete answer:
Cytotaxonomy is a branch of biology taxonomy, which is handling the classification and relationships of organisms utilizing complete studies of chromosomes. The properties (number, structure, and behavior) of chromosomes are of great value in taxonomy, because the chromosome number being the foremost widely used and quoted character in biology. Chromosome numbers are mainly determined at mitosis and quoted because of the diploid number (2n). Another essential taxonomic character is the position of the centromere. Meiotic behavior sometimes shows the heterozygosity of inversions. Cytological data is critical than other taxonomic evidence.

Additional information: The role of cytotaxonomy is extremely important in taxonomic studies. Cytotaxonomy is highly important over physiological taxonomy as this procedure is maintaining the comparative examination of chromosomes and with this method, small variations among the particulars are often detected. DNA is present within every chromosome and the variations in each DNA are liable for the variation among the individuals, species, genus, and everything. When the differences in physiological variation are too small among the particulars of similar species and other higher taxa. Cytotaxonomy may be a part of taxonomic biology that deals with the classification of organisms. Cytotaxonomy classifies these organisms as supporting their function and cellular (DNA) structure.

Note: Chromosomal cytology has been more extensively employed by plant taxonomists instead of animal taxonomists. The Karyotype characterized by chromosome numbers, size, and morphology, is a definite and constant character of every individual species. The amount of shape banding of chromosomes is often determined by using various dissecting and marking techniques; chromosomal taxonomy is often quite useful both in determining the phylogenetic relationships of the taxa also as within the segregation of sibling cryptic species.
