Select the incorrect pair
(a) Numerical taxonomy-all observable characteristics
(b). Cytotaxonomy-Cytological information
(c). Chemotaxonomy-Chromosome number and structure
(d). Cladistic taxonomy-Origin from a common ancestor

Text Solution

Verified by Experts

The correct Answer is:
C
Chemotaxonomy is based upon the characteristics of various chemical constituents of organisms. Chemical constituents of plant species have been found to be unvarying and do not change easily. Chenical characters have also helped in establishing relationships and statistical evaluation of taxonomic information.
