Study Notes
Zoology Questions - Summary
- Correctly written term: Earliest name should be used, this is the Law of Priority.
- Homonymia: A single name cannot be used for 2 different taxa.
- Binomial System Classification: Organism classification based on overall similarity.
- Whittaker's Classification: Recommended 5 Kingdoms for organisms.
- Geographic Isolation: Morphological differences can exist even if species can exchange genes.
- Biosystematics: Term for modern science of classification.
- Taxonomic categories (incorrect): "Breed" is not a taxonomic category.
-
Order and Genus Belonging:
- Trypanosoma belongs to Kinetoplastida
- Leishmania belongs to Kinetoplastida
