Cytotaxonomy is a branch of taxonomy that uses the characteristics of cellular structures to classify organisms. In cytotaxonomy, the chromosomal configuration of an organism is the most widely used parameter to infer the relationship between two organisms. The inference of species relationships is based on the assumption that closely related species share similar characteristics in their chromosomal setup (referred to as karyotype). By analysing the similarities and differenc… WebIn this method, a crude protein extract of a particular plant taxa (antigen), is injected into the blood stream of an experimental animal, usually a rabbit or a rat, to develop …
