Master NEET Zoology with topic-wise questions. Tailored for NEET students, these questions strengthen your Biology preparation.
Which of the following is NOT a characteristic typically associated with organisms that predominantly reproduce asexually?
Rapid population growth in stable environments
Adaptation to narrow ecological niches
High genetic diversity within populations
Reduced energy expenditure on mate finding
Certain plants can reproduce both sexually and asexually. Under which of the following environmental conditions would asexual reproduction be MOST advantageous?
Unstable environment with frequent disturbances
Environment with high pathogen pressure
Environment with limited resources and high competition
Stable environment with abundant resources
The concept of punctuated equilibrium challenges the traditional view of evolution by suggesting:
Evolution proceeds at a constant, gradual rate.
Long periods of stasis punctuated by rapid bursts of evolutionary change.
Evolutionary changes occur only in small, isolated populations.
Acquired characteristics are inherited and drive evolutionary change.
Which observation MOST directly challenges the idea of a universally applicable โmolecular clockโ for dating evolutionary divergence?
Fossil evidence sometimes contradicts molecular clock estimates.
Mutation rates can be influenced by environmental factors.
Different genes evolve at different rates, even within the same lineage.
Horizontal gene transfer can introduce new genes into a lineage.
The evolutionary significance of the Burgess Shale fossils lies primarily in:
Providing evidence for the earliest forms of life on Earth.
Demonstrating a rapid diversification of body plans during the Cambrian explosion.
Showing the transition from aquatic to terrestrial life.
Illustrating the co-evolution of plants and animals.
The concept of 'adaptive radiation' is BEST exemplified by:
The evolution of antibiotic resistance in bacteria.
The development of camouflage in a prey species.
Darwin's finches on the Galapagos Islands developing diverse beak shapes for different food sources.
The gradual increase in size of a particular species over generations.
Which scenario would MOST likely lead to allopatric speciation?
Two closely related plant species hybridizing in a shared habitat.
A mutation arising in a single individual within a population.
A river changing course and dividing a population of rodents into two isolated groups.
Seasonal variations in food availability leading to different feeding behaviors within a bird species.
The presence of homologous structures in different species suggests:
Convergent evolution
Analogous adaptations
Shared ancestry
Independent mutations
Hardy-Weinberg equilibrium assumes all of the following EXCEPT:
No mutation
No gene flow
Random mating
Non-random mating
Which of the following is NOT a crucial assumption of Hardy-Weinberg equilibrium?
No mutation
Random mating
No gene flow
No natural selection
