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

  1. Gene Flow

  2. Genetic Drift

  3. Natural Selection

  4. Mutation


Correct Option: A
Explanation:

Gene Flow is the movement of alleles from one population to another, typically through migration or interbreeding.

Which of the following is NOT a mechanism of Gene Flow?

  1. Migration

  2. Interbreeding

  3. Mutation

  4. Gene Conversion


Correct Option: C
Explanation:

Mutation is not a mechanism of Gene Flow, as it does not involve the movement of alleles between populations.

What is the effect of Gene Flow on genetic diversity?

  1. Increases genetic diversity

  2. Decreases genetic diversity

  3. No effect on genetic diversity

  4. Depends on the direction of Gene Flow


Correct Option: A
Explanation:

Gene Flow typically increases genetic diversity by introducing new alleles into a population.

What is the term used to describe the reduction in genetic diversity due to Gene Flow?

  1. Genetic Drift

  2. Founder Effect

  3. Bottleneck Effect

  4. Gene Swamping


Correct Option: D
Explanation:

Gene Swamping is the reduction in genetic diversity due to the introduction of a large number of alleles from another population.

Which of the following is an example of Gene Flow?

  1. Migration of birds from one region to another

  2. Interbreeding between two different species

  3. Mutation in a single gene

  4. Natural selection favoring a particular allele


Correct Option: A
Explanation:

Migration of birds from one region to another is an example of Gene Flow, as it involves the movement of alleles between populations.

What is the term used to describe the movement of alleles from a small population to a larger population?

  1. Gene Flow

  2. Genetic Drift

  3. Founder Effect

  4. Bottleneck Effect


Correct Option: C
Explanation:

Founder Effect is the movement of alleles from a small population to a larger population, typically when a small group of individuals colonizes a new area.

What is the term used to describe the movement of alleles from a large population to a smaller population?

  1. Gene Flow

  2. Genetic Drift

  3. Founder Effect

  4. Bottleneck Effect


Correct Option: D
Explanation:

Bottleneck Effect is the movement of alleles from a large population to a smaller population, typically when a population experiences a sudden reduction in size.

Which of the following factors can affect the rate of Gene Flow?

  1. Distance between populations

  2. Migration rates

  3. Interbreeding rates

  4. All of the above


Correct Option: D
Explanation:

The rate of Gene Flow can be affected by a variety of factors, including the distance between populations, migration rates, and interbreeding rates.

What is the term used to describe the movement of alleles between two populations that are geographically separated?

  1. Gene Flow

  2. Genetic Drift

  3. Founder Effect

  4. Bottleneck Effect


Correct Option: A
Explanation:

Gene Flow is the movement of alleles between two populations that are geographically separated, typically through migration or interbreeding.

Which of the following is an example of Gene Flow between two geographically separated populations?

  1. Migration of birds from one region to another

  2. Interbreeding between two different species

  3. Mutation in a single gene

  4. Natural selection favoring a particular allele


Correct Option: A
Explanation:

Migration of birds from one region to another is an example of Gene Flow between two geographically separated populations, as it involves the movement of alleles between populations that are separated by a geographic barrier.

What is the term used to describe the movement of alleles between two populations that are not geographically separated?

  1. Gene Flow

  2. Genetic Drift

  3. Founder Effect

  4. Bottleneck Effect


Correct Option: A
Explanation:

Gene Flow is the movement of alleles between two populations that are not geographically separated, typically through interbreeding.

Which of the following is an example of Gene Flow between two populations that are not geographically separated?

  1. Migration of birds from one region to another

  2. Interbreeding between two different species

  3. Mutation in a single gene

  4. Natural selection favoring a particular allele


Correct Option: B
Explanation:

Interbreeding between two different species is an example of Gene Flow between two populations that are not geographically separated, as it involves the movement of alleles between populations that are not separated by a geographic barrier.

What is the term used to describe the movement of alleles from one species to another?

  1. Gene Flow

  2. Genetic Drift

  3. Founder Effect

  4. Bottleneck Effect


Correct Option: A
Explanation:

Gene Flow is the movement of alleles from one species to another, typically through hybridization or introgression.

Which of the following is an example of Gene Flow from one species to another?

  1. Migration of birds from one region to another

  2. Interbreeding between two different species

  3. Mutation in a single gene

  4. Natural selection favoring a particular allele


Correct Option: B
Explanation:

Interbreeding between two different species is an example of Gene Flow from one species to another, as it involves the movement of alleles between populations that are separated by a species barrier.

What is the term used to describe the movement of alleles from a domesticated species to a wild species?

  1. Gene Flow

  2. Genetic Drift

  3. Founder Effect

  4. Bottleneck Effect


Correct Option: A
Explanation:

Gene Flow is the movement of alleles from a domesticated species to a wild species, typically through hybridization or introgression.

Which of the following is an example of Gene Flow from a domesticated species to a wild species?

  1. Migration of birds from one region to another

  2. Interbreeding between two different species

  3. Mutation in a single gene

  4. Natural selection favoring a particular allele


Correct Option:
Explanation:

Interbreeding between a domesticated species and a wild species is an example of Gene Flow from a domesticated species to a wild species, as it involves the movement of alleles between populations that are separated by a domestication barrier.
