Question

Taxonomic keys are based on

• A. Morphological characters
• B. Reproductive characters
• C. Anatomical characters
• D. Contrasting characters

Hint:

In taxonomic classification, contrasting characters are those that show clear differences between species, making identification easier through a dichotomous key.

Answer 1

The Correct Option is D

Taxonomic keys are used in the classification and identification of organisms. These keys are based on contrasting characters, which are traits that differ between organisms. These contrasting characters are used to distinguish between different species or groups.
- Morphological characters are physical traits such as size, shape, and structure, but the key is based on contrasting traits that highlight differences.
- Reproductive characters also help in classification, but the basis of taxonomic keys is to contrast different visible traits, not just reproductive features.
- Anatomical characters refer to the internal structure of organisms, but again, the focus is on contrasting, visible characters.
- Contrasting characters are the most essential aspect of taxonomic keys, as they provide distinct, oppositional traits for easy identification.
Thus, the correct answer is (4) Contrasting characters.
