What is the term used to describe the variation in the genetic makeup of a species?

  1. Genetic drift

  2. Genetic diversity

  3. Genetic engineering

  4. Genetic recombination


Correct Option: B
Explanation:

Genetic diversity refers to the variation in the genetic makeup of a species, encompassing differences in DNA sequences, genes, and chromosomes.

Which of the following is NOT a primary threat to genetic diversity?

  1. Habitat loss

  2. Climate change

  3. Selective breeding

  4. Natural selection


Correct Option: D
Explanation:

Natural selection is a natural process that drives evolution and does not directly threaten genetic diversity. Habitat loss, climate change, and selective breeding are all human-induced factors that can reduce genetic diversity.

Which conservation strategy aims to protect genetic diversity by maintaining populations in their natural habitats?

  1. Ex situ conservation

  2. In situ conservation

  3. Cryopreservation

  4. Gene banks


Correct Option: B
Explanation:

In situ conservation involves protecting species and their genetic diversity within their natural habitats, preserving their ecological interactions and evolutionary processes.

What is the term used to describe the process by which genetic diversity is lost from a population?

  1. Genetic drift

  2. Genetic recombination

  3. Gene flow

  4. Mutation


Correct Option: A
Explanation:

Genetic drift refers to the random fluctuation of gene frequencies in a population, leading to the loss of genetic diversity over time.

Which of the following is NOT a benefit of genetic diversity?

  1. Increased adaptability to environmental changes

  2. Enhanced resistance to diseases and pests

  3. Reduced risk of inbreeding depression

  4. Increased vulnerability to extinction


Correct Option: D
Explanation:

Genetic diversity is crucial for the survival and resilience of species, reducing their vulnerability to extinction by providing a buffer against environmental changes and diseases.

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

  1. Gene flow

  2. Genetic drift

  3. Mutation

  4. Recombination


Correct Option: A
Explanation:

Gene flow refers to the transfer of genetic material between populations, which can occur through migration, pollination, or other mechanisms.

Which conservation strategy involves storing genetic material, such as seeds or DNA samples, for future use?

  1. Ex situ conservation

  2. In situ conservation

  3. Cryopreservation

  4. Gene banks


Correct Option: D
Explanation:

Gene banks are facilities that store genetic material, such as seeds, tissues, or DNA samples, for conservation and research purposes.

What is the term used to describe the loss of genetic diversity due to the reduction in population size?

  1. Bottleneck effect

  2. Founder effect

  3. Genetic drift

  4. Mutation


Correct Option: A
Explanation:

The bottleneck effect refers to the reduction in genetic diversity that occurs when a population experiences a severe reduction in size, leading to the loss of genetic variants.

Which of the following is NOT a consequence of reduced genetic diversity?

  1. Increased susceptibility to diseases

  2. Reduced adaptability to environmental changes

  3. Increased risk of inbreeding depression

  4. Enhanced reproductive success


Correct Option: D
Explanation:

Reduced genetic diversity can have detrimental effects on a population, including increased susceptibility to diseases, reduced adaptability, and increased risk of inbreeding depression. It does not lead to enhanced reproductive success.

What is the term used to describe the process by which genetic material is exchanged between homologous chromosomes during meiosis?

  1. Genetic recombination

  2. Gene flow

  3. Mutation

  4. Genetic drift


Correct Option: A
Explanation:

Genetic recombination involves the exchange of genetic material between homologous chromosomes during meiosis, resulting in the creation of new gene combinations.

Which conservation strategy focuses on protecting genetic diversity by establishing and managing protected areas?

  1. Ex situ conservation

  2. In situ conservation

  3. Cryopreservation

  4. Gene banks


Correct Option: B
Explanation:

In situ conservation involves protecting species and their genetic diversity within their natural habitats, including the establishment and management of protected areas.

What is the term used to describe the introduction of new genetic material into a population?

  1. Gene flow

  2. Genetic drift

  3. Mutation

  4. Recombination


Correct Option: A
Explanation:

Gene flow refers to the movement of genes from one population to another, which can introduce new genetic material and increase genetic diversity.

Which of the following is NOT a benefit of maintaining genetic diversity in agricultural crops?

  1. Increased resistance to pests and diseases

  2. Improved crop yield and quality

  3. Enhanced adaptability to climate change

  4. Increased susceptibility to environmental stresses


Correct Option: D
Explanation:

Maintaining genetic diversity in agricultural crops provides numerous benefits, including increased resistance to pests and diseases, improved crop yield and quality, and enhanced adaptability to climate change. It does not lead to increased susceptibility to environmental stresses.

What is the term used to describe the process by which genetic material is passed from parents to offspring?

  1. Heredity

  2. Inheritance

  3. Gene flow

  4. Mutation


Correct Option: B
Explanation:

Inheritance refers to the process by which genetic material, in the form of genes, is passed from parents to their offspring.

Which conservation strategy involves breeding and raising individuals in captivity for eventual release into the wild?

  1. Ex situ conservation

  2. In situ conservation

  3. Cryopreservation

  4. Gene banks


Correct Option: A
Explanation:

Ex situ conservation involves breeding and raising individuals in captivity for eventual release into the wild, with the aim of preserving genetic diversity and reintroducing species to their natural habitats.
