Class 10 Quiz Level 3 (Difficult) – Heredity and Evolution
Total questions: 10
1.
Which of the following is a consequence of gene flow between populations?
Topic:
Evolution
Deselect Answer
Increased genetic diversity within populations
Increased genetic divergence between populations
Increased mutation rates
Increased genetic drift
None
2.
Which evolutionary concept is illustrated by the gradual accumulation of small genetic changes in a population over long periods?
Topic:
Evolution
Deselect Answer
Punctuated equilibrium
Gradualism
Genetic drift
Adaptive radiation
None
3.
What is the primary difference between allopatric and sympatric speciation?
Topic:
Evolution
Deselect Answer
Allopatric speciation requires geographic isolation, while sympatric speciation occurs without geographic isolation.
Allopatric speciation involves genetic drift, while sympatric speciation involves natural selection.
Allopatric speciation occurs rapidly, while sympatric speciation occurs slowly.
Allopatric speciation is common in plants, while sympatric speciation is common in animals.
None
4.
Which of the following best describes a ring species?
Topic:
Evolution
Deselect Answer
A single species with a circular distribution and continuous gene flow
A single species that has undergone allopatric speciation
A species that exhibits both radial and bilateral symmetry
A species with no genetic variation
None
5.
Which of the following processes can lead to the rapid evolution of a population in response to a sudden environmental change?
Topic:
Evolution
Deselect Answer
Genetic drift
Gene flow
Bottleneck effect
Natural selection
None
6.
Which of the following best describes the Red Queen Hypothesis?
Topic:
Evolution
Deselect Answer
Species must constantly adapt and evolve to survive while pitted against ever-evolving opposing species.
Species evolve due to random genetic drift and not because of natural selection.
Evolutionary change occurs in rapid bursts followed by long periods of stability.
Species remain genetically static until environmental changes force adaptation.
None
7.
In a polygenic inheritance pattern, if three genes (A, B, and C) each with two alleles contribute additively to the trait of height in plants, how many different phenotypic classes can be observed in the offspring?
Topic:
Heredity
Deselect Answer
3
4
5
7
None
8.
Which of the following is an example of a prezygotic isolating mechanism?
Topic:
Evolution
Deselect Answer
Reduced hybrid fertility
Temporal isolation
Hybrid inviability
Hybrid breakdown
None
9.
Which of the following best describes the role of a spliceosome?
Topic:
Heredity
Deselect Answer
It initiates DNA replication.
It synthesizes proteins.
It removes introns from pre-mRNA.
It facilitates chromosomal crossover.
None
10.
Which concept describes the ability of a single gene to affect multiple phenotypic traits?
Topic:
Evolution
Deselect Answer
Epistasis
Pleiotropy
Polygenic inheritance
Codominance
None
