Master NEET Zoology with topic-wise questions. Tailored for NEET students, these questions strengthen your Biology preparation.
Which evolutionary mechanism involves the movement of genes between populations?
Mutation
Genetic drift
Gene flow
Natural selection
The 'Out of Africa' hypothesis suggests that modern humans:
Evolved independently in different regions
Originated in Asia and migrated to other continents
Originated in Africa and migrated to other continents
Evolved from Neanderthals in Europe
Which of the following conditions would cause the observed genotype frequencies in a population to deviate significantly from Hardy-Weinberg expectations, assuming that the population was initially in equilibrium?
Random mating within a large population
Absence of mutation
No natural selection
Differential migration of certain genotypes
Which of the following correctly describes the life cycle of Petromyzon?
Spawns in freshwater, larval stage in freshwater, adult stage in the ocean
Spawns in the ocean, larval stage in the ocean, adult stage in freshwater
Spawns in freshwater, larval stage in the ocean, adult stage in freshwater
Spawns in the ocean, larval stage in freshwater, adult stage in the ocean
The migration of Petromyzon from freshwater to the ocean after metamorphosis is an example of:
Diadromy
Anadromy
Catadromy
Potamodromy

In a random mating population in equilibrium, which of the following brings about a change in gene frequency in non-directional manner?
Natural selection
Mutation
Gene flow
Genetic drift

If both (A) and (R) are true and (R ) is correct explanation of (A)
If both (A) and (R ) are true and (R) is not correct explanation of (A)
If (A) is true but (R ) is false
If (A) is false but ( R ) is true
Which one of these organisms shows all the following properties? I. Exclusively marine habitat II. Migration to fresh water for spawning III. After spawning, within a few days, it dies
