Master NEET Zoology with topic-wise questions. Tailored for NEET students, these questions strengthen your Biology preparation.
Which of the following events is NOT associated with the process of spermatogenesis?
Formation of a polar body
Differentiation of spermatids into spermatozoa
Meiotic divisions
Release of spermatozoa into the seminiferous tubules
The process of parthenogenesis involves the development of an organism from an unfertilized egg. Which statement is TRUE regarding the genetic makeup of an organism produced through parthenogenesis?
It is genetically identical to the mother, except for any mutations that may have occurred.
It inherits half its chromosomes from the mother and half from the father.
It is genetically distinct from both the mother and the father.
It inherits all its chromosomes from the father.
The development of which anatomical feature is MOST closely linked to the evolution of language in hominins?
Enlarged brow ridges
Descended larynx
Increased prognathism
Reduced sagittal crest
The 'multiregional hypothesis' for the origin of modern humans proposes which of the following?
Homo sapiens evolved solely in Africa and then replaced all other hominin populations worldwide.
Homo sapiens evolved simultaneously in different regions from earlier hominin populations, with gene flow maintaining species cohesion.
Neanderthals were the direct ancestors of modern humans.
Homo erectus never left Africa.
The Hardy-Weinberg principle describes the conditions under which allele and genotype frequencies in a population remain constant. Which of the following is NOT an assumption of the Hardy-Weinberg principle?
No mutations occur.
No gene flow occurs between populations.
Natural selection does not act on the population.
Non-random mating, such as assortative mating, occurs.
Adaptive radiation is a process of rapid diversification from an ancestral species. Which of the following is NOT a characteristic feature of adaptive radiation?
Common ancestry of the diversified species
Phenotype-environment correlation
Trait utility
Slow and gradual diversification over time
Which of the following is NOT a characteristic of asexual reproduction?
Produces genetically identical offspring
Involves the fusion of gametes
Can occur through methods like budding and fragmentation

Which form of asexual reproduction involves the development of a new organism from an outgrowth or bud due to cell division at one particular site?
Fragmentation
Binary fission
Budding
Spore formation
