Prepare for NEET with Botany-specific practice questions. Covering all major Botany chapters, this is perfect for your NEET Biology needs.
A taxonomist discovers a new species of insect. Phylogenetic analysis places it within the order Coleoptera, but its morphology is so unique it warrants a new family. Which of the following taxonomic ranks will not necessarily be assigned a new name for this insect?
Order
Family
Genus
Species
Which of the following statements about chemotaxonomy is incorrect?
It uses chemical constituents of organisms for taxonomic classification.
It can be useful in distinguishing closely related species with similar morphologies.
It can help in understanding evolutionary relationships.
It relies solely on morphological characteristics for classification.
The polyphyletic grouping of organisms is based on:
Shared ancestral characteristics.
Homologous characteristics derived from a common ancestor.
Analogous characteristics due to convergent evolution.
A combination of ancestral and derived characteristics.
In numerical taxonomy, the principle of 'overall similarity' emphasizes:
Prioritizing specific key characters over others.
Focusing on derived characteristics rather than ancestral ones.
Considering a large number of characters and giving equal weight to each.
Using only morphological characteristics for analysis.
Which of the following is not a limitation of classical taxonomy?
It relies heavily on morphological characteristics, which can be subject to convergent evolution.
It may not accurately reflect evolutionary relationships.
It can be difficult to distinguish between homologous and analogous traits.
It incorporates molecular data for a more comprehensive analysis.
A scientist is constructing a phylogenetic tree using cladistics. Which type of character would be considered the most informative for resolving evolutionary relationships within a group?
Plesiomorphy
Symplesiomorphy
Autapomorphy
Synapomorphy
