Each character is given equal importance and at the same time hundreds of characters can be considered in
1 cytotaxonomy
2 morphotaxonomy
3 chemotaxonomy
4 numerical taxonomy
Explanation:
(d)Numerical taxonomy evaluates resemblances and differences or primitiveness and advancement through statistical methods based on a large number of characters obtained from all disciplines of biology. This is followed by assigning them number and code of computer like plus $\left( + \right)$ and minus $\left( - \right)$ followed by computer analysis. In this way, each character is given equal importance and at the same time hundreds of characters can be considered.

Select the incorrect pair.
1 Numerical taxonomy - All observable characteristics
2 Cytotaxonomy - Cytological information
3 Chemotaxonomy - Chromosome number and structure
4 Cladistic taxonomy - Origin from a common ancestor
Explanation:
(c) Chemotaxonomy is based upon the characteristics of various contituents of organisms.
