Master NEET Zoology with topic-wise questions. Tailored for NEET students, these questions strengthen your Biology preparation.
Which type of anatomical structures provide evidence for divergent evolution?
Analogous structures
Homologous structures
Vestigial structures
Rudimentary structures
The wings of a butterfly and the wings of a bat are examples of:
Homologous structures
Analogous structures
Vestigial structures
Fossil evidence
Which of these provides evidence of a common ancestor for vertebrates?
Different numbers of limbs in different vertebrates
Varying body sizes among vertebrates
Presence of gill slits in vertebrate embryos
Different feeding habits in vertebrates
Structures that are reduced in size and have no apparent function are called:
Homologous structures
Analogous structures
Vestigial structures
Adaptive structures
The original antigenic sin phenomenon can hinder the effectiveness of vaccination against rapidly evolving viruses. Which of the following best describes this phenomenon?
The vaccine inadvertently induces an autoimmune response.
The pathogen develops resistance to the vaccine-induced antibodies.
The immune system preferentially utilizes memory cells against previously encountered strains, even if they are not a perfect match for the current strain.
The vaccine fails to induce a strong enough primary immune response.
Which of the following conditions is NOT required for a population to be in Hardy-Weinberg equilibrium?
Random mating
No mutation
No gene flow
Small population size
The Hardy-Weinberg principle states that allele and genotype frequencies in a population will remain constant from generation to generation in the absence of other evolutionary influences. This principle provides a baseline for:
Predicting the exact genetic makeup of future generations
Determining the rate of mutation in a population
Determining whether evolution is occurring
Calculating the number of individuals in a population
Which of the following is NOT a key factor influencing the process of natural selection?
Variation within a population
Inheritance of traits
Differential reproductive success
Equal survival rates for all individuals
Genetic drift is most likely to have a significant impact on which type of population?
Large and diverse
Small and isolated
Migratory populations
Populations with high mutation rates
