What is the term for the change in the frequency of alleles in a population over time?

  1. Genetic drift

  2. Natural selection

  3. Mutation

  4. Gene flow


Correct Option: A
Explanation:

Genetic drift is the change in the frequency of alleles in a population over time due to random chance.

Which of the following is NOT a mechanism of evolution?

  1. Natural selection

  2. Artificial selection

  3. Genetic drift

  4. Gene flow


Correct Option: B
Explanation:

Artificial selection is the process by which humans select for certain traits in animals or plants, while natural selection is the process by which organisms with advantageous traits are more likely to survive and reproduce.

What is the term for the movement of alleles from one population to another?

  1. Genetic drift

  2. Natural selection

  3. Mutation

  4. Gene flow


Correct Option: D
Explanation:

Gene flow is the movement of alleles from one population to another, which can occur through migration, mating, or other means.

Which of the following is NOT a type of genetic variation?

  1. Single nucleotide polymorphism (SNP)

  2. Insertion/deletion polymorphism (InDel)

  3. Copy number variation (CNV)

  4. Linkage disequilibrium (LD)


Correct Option: D
Explanation:

Linkage disequilibrium is the non-random association of alleles at different loci, while SNP, InDel, and CNV are all types of genetic variation.

What is the term for the proportion of individuals in a population that carry a particular allele?

  1. Allele frequency

  2. Genotype frequency

  3. Phenotype frequency

  4. Hardy-Weinberg equilibrium


Correct Option: A
Explanation:

Allele frequency is the proportion of individuals in a population that carry a particular allele.

Which of the following is NOT a condition for Hardy-Weinberg equilibrium?

  1. No mutation

  2. No gene flow

  3. Random mating

  4. No genetic drift


Correct Option: D
Explanation:

Genetic drift is the change in the frequency of alleles in a population over time due to random chance, while the other conditions are necessary for Hardy-Weinberg equilibrium.

What is the term for the process by which new alleles are introduced into a population?

  1. Mutation

  2. Gene flow

  3. Genetic drift

  4. Natural selection


Correct Option: A
Explanation:

Mutation is the process by which new alleles are introduced into a population.

Which of the following is NOT a type of mutation?

  1. Single nucleotide polymorphism (SNP)

  2. Insertion/deletion polymorphism (InDel)

  3. Copy number variation (CNV)

  4. Transposable element insertion


Correct Option: D
Explanation:

Transposable element insertion is a type of genetic variation, but it is not a type of mutation.

What is the term for the study of the genetic variation within a population?

  1. Population genetics

  2. Molecular genetics

  3. Cytogenetics

  4. Genomics


Correct Option: A
Explanation:

Population genetics is the study of the genetic variation within a population.

Which of the following is NOT a method for studying population genetics?

  1. DNA sequencing

  2. PCR

  3. Gel electrophoresis

  4. Hardy-Weinberg equilibrium


Correct Option: D
Explanation:

Hardy-Weinberg equilibrium is a theoretical model used to study population genetics, but it is not a method for studying population genetics.

What is the term for the process by which natural selection acts on a population?

  1. Directional selection

  2. Stabilizing selection

  3. Disruptive selection

  4. Sexual selection


Correct Option:
Explanation:

Natural selection is the process by which natural selection acts on a population.

Which of the following is NOT a type of natural selection?

  1. Directional selection

  2. Stabilizing selection

  3. Disruptive selection

  4. Artificial selection


Correct Option: D
Explanation:

Artificial selection is the process by which humans select for certain traits in animals or plants, while natural selection is the process by which organisms with advantageous traits are more likely to survive and reproduce.

What is the term for the process by which sexual selection acts on a population?

  1. Mate choice

  2. Intrasexual competition

  3. Parental investment

  4. Sexual conflict


Correct Option:
Explanation:

Sexual selection is the process by which sexual selection acts on a population.

Which of the following is NOT a type of sexual selection?

  1. Mate choice

  2. Intrasexual competition

  3. Parental investment

  4. Natural selection


Correct Option: D
Explanation:

Natural selection is the process by which organisms with advantageous traits are more likely to survive and reproduce, while sexual selection is the process by which sexual selection acts on a population.

What is the term for the process by which organisms evolve to better adapt to their environment?

  1. Adaptation

  2. Natural selection

  3. Genetic drift

  4. Gene flow


Correct Option: A
Explanation:

Adaptation is the process by which organisms evolve to better adapt to their environment.
