What is the primary goal of genetic engineering in the context of biodiversity preservation?

  1. To enhance crop yields and increase food production

  2. To create genetically modified organisms (GMOs) for medical research

  3. To modify organisms to adapt to changing environmental conditions

  4. To preserve and protect the diversity of life on Earth


Correct Option: D
Explanation:

Genetic engineering in the context of biodiversity preservation aims to utilize genetic techniques to conserve and protect the diversity of species and ecosystems, rather than focusing on agricultural or medical applications.

Which of the following is a potential benefit of genetic engineering in biodiversity conservation?

  1. Increased resistance to pests and diseases in crops

  2. Enhanced tolerance to environmental stresses in plants

  3. Accelerated reproduction rates in endangered species

  4. All of the above


Correct Option: D
Explanation:

Genetic engineering offers various potential benefits in biodiversity conservation, including increased resistance to pests and diseases, enhanced tolerance to environmental stresses, and accelerated reproduction rates in endangered species.

What is the main concern associated with the use of genetic engineering in biodiversity conservation?

  1. The potential for unintended consequences on ecosystems

  2. The risk of creating superweeds and superpests

  3. The ethical implications of modifying organisms

  4. All of the above


Correct Option: D
Explanation:

The use of genetic engineering in biodiversity conservation raises concerns about unintended consequences on ecosystems, the creation of superweeds and superpests, and ethical considerations related to modifying organisms.

How can genetic engineering be used to protect endangered species?

  1. By introducing genetic traits that enhance their survival and reproduction

  2. By creating genetically modified organisms that can serve as surrogate hosts

  3. By developing genetic techniques to prevent poaching and habitat destruction

  4. Both A and B


Correct Option: D
Explanation:

Genetic engineering can be used to protect endangered species by introducing genetic traits that enhance their survival and reproduction, as well as by creating genetically modified organisms that can serve as surrogate hosts for endangered species.

What is the concept of genetic rescue in the context of biodiversity conservation?

  1. The use of genetic engineering to introduce new genetic material into a population

  2. The translocation of individuals from one population to another to increase genetic diversity

  3. The selective breeding of individuals with desirable traits to improve population fitness

  4. The establishment of captive breeding programs for endangered species


Correct Option: A
Explanation:

Genetic rescue involves the use of genetic engineering to introduce new genetic material into a population, typically to increase genetic diversity and improve the population's ability to adapt to changing environmental conditions.

Which of the following is an example of genetic engineering being used to preserve biodiversity?

  1. The development of genetically modified crops that are resistant to pests and diseases

  2. The creation of genetically modified organisms that can produce biofuels

  3. The engineering of bacteria to clean up oil spills

  4. The development of genetically modified mosquitoes to control malaria


Correct Option: A
Explanation:

The development of genetically modified crops that are resistant to pests and diseases is an example of genetic engineering being used to preserve biodiversity, as it reduces the need for chemical pesticides and herbicides, which can harm beneficial insects and wildlife.

What is the role of genetic engineering in the conservation of genetic resources?

  1. It allows for the preservation of genetic diversity in seed banks and gene banks

  2. It enables the development of genetically modified organisms that can tolerate harsh environmental conditions

  3. It facilitates the study of genetic variation and population genetics

  4. All of the above


Correct Option: D
Explanation:

Genetic engineering plays a role in the conservation of genetic resources by allowing for the preservation of genetic diversity, the development of genetically modified organisms that can tolerate harsh environmental conditions, and the study of genetic variation and population genetics.

How can genetic engineering be used to control invasive species?

  1. By introducing genetic traits that make them less competitive

  2. By creating genetically modified organisms that can prey on invasive species

  3. By developing genetic techniques to prevent invasive species from reproducing

  4. Both A and C


Correct Option: D
Explanation:

Genetic engineering can be used to control invasive species by introducing genetic traits that make them less competitive or by developing genetic techniques to prevent them from reproducing.

What is the Cartagena Protocol on Biosafety?

  1. An international agreement that regulates the transboundary movement of living modified organisms (LMOs)

  2. A set of guidelines for the safe use of genetically modified organisms (GMOs)

  3. A treaty that promotes the conservation of biodiversity and sustainable use of genetic resources

  4. A global initiative to raise awareness about the risks of genetic engineering


Correct Option: A
Explanation:

The Cartagena Protocol on Biosafety is an international agreement that regulates the transboundary movement of living modified organisms (LMOs), including genetically modified organisms (GMOs), to ensure their safe handling and use.

What is the role of public engagement and stakeholder involvement in genetic engineering and biodiversity conservation?

  1. To ensure transparency and accountability in decision-making processes

  2. To gather input and feedback from affected communities and stakeholders

  3. To promote informed decision-making and address ethical concerns

  4. All of the above


Correct Option: D
Explanation:

Public engagement and stakeholder involvement play a crucial role in genetic engineering and biodiversity conservation by ensuring transparency, accountability, gathering input and feedback, and promoting informed decision-making that addresses ethical concerns.
