The following points highlight the top five roles of palynology in taxonomy. The roles are: 1. Stenopalynous and Eurypalynous Taxon 2. Family and Tribal Level 3. Generic Level 4. Species and Infra Specific Level 5. Phylogenetic Considerations. Palynology: Role # 1. Stenopalynous and Eurypalynous Taxon: i. Stenopalynous: In many taxon, the type of pollen is characteristic and constant. Such a [...]
The following points highlight the top five characteristics of chromosome. The characteristics are: 1. Chromosome Number 2. Chromosome Size 3. Morphology 4. Behaviour at Meiosis 5. Banding Patterns. Characteristic # 1. Chromosome Number: The number of chromosomes in a species is usually constant and this makes it an important taxonomic character. However there are exceptions where chromosome number varies. These [...]
In this article we will discuss about Fossil:- 1. Role of Fossil 2. Uses of Fossil 3. Types 4. Limitations. Role of Fossil: Fossils have a potentially important role to play in taxonomy and phylogenetics. However, their use and interpretation has its own pitfalls and contentious issues. Under proper conditions, animals, plants and even microorganisms can leave remarkably good traces [...]
