What is the primary goal of Conservation Genetics?

  1. To understand the genetic basis of adaptation.

  2. To identify and protect genetically unique populations.

  3. To develop strategies for managing genetic diversity.

  4. To study the evolutionary history of species.


Correct Option: B
Explanation:

Conservation Genetics aims to identify and protect genetically unique populations, as these populations may contain valuable genetic diversity that is essential for the long-term survival of a species.

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

  1. Habitat loss and fragmentation.

  2. Overexploitation.

  3. Climate change.

  4. Artificial selection.


Correct Option: D
Explanation:

Artificial selection is a human-directed process, while habitat loss and fragmentation, overexploitation, and climate change are natural or human-induced threats to genetic diversity.

What is the term for the loss of genetic diversity within a population?

  1. Genetic drift.

  2. Inbreeding.

  3. Bottleneck effect.

  4. Founder effect.


Correct Option: A
Explanation:

Genetic drift is the random fluctuation of allele frequencies in a population over time, which can lead to the loss of genetic diversity.

Which of the following is NOT a method for conserving genetic diversity?

  1. Habitat protection.

  2. Captive breeding.

  3. Gene banks.

  4. Assisted gene flow.


Correct Option: D
Explanation:

Assisted gene flow is a controversial method that involves the intentional movement of individuals between populations to increase genetic diversity, while habitat protection, captive breeding, and gene banks are all established methods for conserving genetic diversity.

What is the term for the genetic variation that exists within a population?

  1. Genetic diversity.

  2. Allelic diversity.

  3. Heterozygosity.

  4. Genetic drift.


Correct Option: A
Explanation:

Genetic diversity refers to the variation in genetic material within a population, including variation in genes, alleles, and genotypes.

Which of the following is NOT a type of genetic marker used in Conservation Genetics?

  1. Microsatellites.

  2. Single nucleotide polymorphisms (SNPs).

  3. Restriction fragment length polymorphisms (RFLPs).

  4. Karyotypes.


Correct Option: D
Explanation:

Karyotypes are used to study chromosome structure and abnormalities, while microsatellites, SNPs, and RFLPs are all types of genetic markers used to study genetic variation and diversity.

What is the term for the process by which a small number of individuals colonize a new area and establish a new population?

  1. Founder effect.

  2. Bottleneck effect.

  3. Genetic drift.

  4. Inbreeding.


Correct Option: A
Explanation:

The founder effect occurs when a small number of individuals colonize a new area and establish a new population, which can lead to a loss of genetic diversity due to the limited genetic variation in the founding individuals.

Which of the following is NOT a consequence of inbreeding?

  1. Increased homozygosity.

  2. Reduced genetic diversity.

  3. Increased susceptibility to disease.

  4. Increased fitness.


Correct Option: D
Explanation:

Inbreeding typically leads to increased homozygosity, reduced genetic diversity, and increased susceptibility to disease, while increased fitness is not a consequence of inbreeding.

What is the term for the rapid decline in the population size of a species?

  1. Bottleneck effect.

  2. Founder effect.

  3. Genetic drift.

  4. Inbreeding.


Correct Option: A
Explanation:

The bottleneck effect occurs when a population experiences a rapid decline in size, which can lead to a loss of genetic diversity due to the random loss of alleles.

Which of the following is NOT a type of conservation unit used to protect genetic diversity?

  1. National parks.

  2. Wildlife sanctuaries.

  3. Biosphere reserves.

  4. Gene banks.


Correct Option: D
Explanation:

Gene banks are facilities that store genetic material, such as DNA or seeds, for the purpose of preserving genetic diversity, while national parks, wildlife sanctuaries, and biosphere reserves are all types of conservation units used to protect natural habitats and ecosystems.

What is the term for the process by which genetic diversity is lost from a population due to the random loss of alleles?

  1. Genetic drift.

  2. Inbreeding.

  3. Bottleneck effect.

  4. Founder effect.


Correct Option: A
Explanation:

Genetic drift is the random fluctuation of allele frequencies in a population over time, which can lead to the loss of genetic diversity.

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

  1. Increased adaptability to environmental change.

  2. Reduced susceptibility to disease.

  3. Increased reproductive success.

  4. Increased vulnerability to extinction.


Correct Option: D
Explanation:

Genetic diversity typically increases a population's adaptability to environmental change, reduces susceptibility to disease, and increases reproductive success, while increased vulnerability to extinction is not a benefit of genetic diversity.

What is the term for the genetic variation that exists between populations of a species?

  1. Genetic diversity.

  2. Allelic diversity.

  3. Heterozygosity.

  4. Population differentiation.


Correct Option: D
Explanation:

Population differentiation refers to the genetic variation that exists between populations of a species, which can be caused by genetic drift, natural selection, or other factors.

Which of the following is NOT a method for measuring genetic diversity?

  1. Allelic richness.

  2. Heterozygosity.

  3. Genetic distance.

  4. Effective population size.


Correct Option: D
Explanation:

Effective population size is a measure of the number of individuals in a population that contribute to the next generation, while allelic richness, heterozygosity, and genetic distance are all methods for measuring genetic diversity.

What is the term for the process by which genetic diversity is increased through the introduction of new alleles into a population?

  1. Gene flow.

  2. Mutation.

  3. Recombination.

  4. Genetic drift.


Correct Option: A
Explanation:

Gene flow is the movement of genetic material between populations, which can increase genetic diversity by introducing new alleles into a population.
