Artificial Selection: Selective Breeding

What is selective breeding?

• Selective breeding is the process of breeding organisms without considering their traits.

• Selective breeding is the process of breeding only organisms with undesirable traits.

• Selective breeding involves randomly choosing organisms to breed.

• Selective breeding is the process of choosing specific organisms with desirable traits to breed.

Give an example of selective breeding in plants.

• Crossing plants with different sized fruits.

• Breeding plants to create more varieties.

• Breeding plants with large sized fruits.

• Breeding plants randomly without any specific goal.

How does selective breeding differ from natural selection?

• Selective breeding is random.

• Selective breeding leads to genetic diversity.

• Selective breeding is controlled by humans.

• Selective breeding occurs in the wild.

What are some advantages of selective breeding?

• Increased productivity, disease resistance, improved quality.

• Decreased productivity, increased disease susceptibility, worsened quality

• Slower breeding process, reduced disease resistance, lower quality.

• Unpredictable outcomes, decreased productivity, more genetic diversity.

What are some disadvantages of selective breeding?

• Decreased risk of genetic diseases.

• Increased genetic diversity.

• Reduced genetic diversity, increased risk of genetic diseases.

• Positive impact on the overall ecosystem.

Explain the role of humans in selective breeding.

• Humans only breed organisms with undesirable traits.

• Humans select organisms with desirable traits to reproduce, leading to the inheritance of those traits in offspring.

• Humans randomly select organisms for breeding without considering traits.

• Humans have no impact on the breeding process.

How can selective breeding lead to loss of genetic diversity?

• New alleles are added to the population.

• Only selected alleles are kept in the population.

• Selective breeding always results in genetic mutations leading to reduced diversity.

• Selective breeding has no impact on genetic diversity.

Discuss the ethical considerations surrounding selective breeding.

• Reduces genetic diversity so imbalances the ecosystem.

• There are no concerns about animal welfare in selective breeding.

• Selective breeding has no impact on genetic diversity.

• Ethical considerations surrounding selective breeding are irrelevant.

What are some common traits that are often selected for in animals through selective breeding?

• Decreased size, slower growth rate, weakened disease resistance

• Lower milk or egg production, specific coat colors or patterns

• Enhanced smell, improved hearing, specific eye color

• Increased size, improved growth rate, enhanced disease resistance, higher milk or egg production, specific coat colors or patterns

How has selective breeding impacted agriculture and food production?

• Selective breeding has negatively impacted agriculture and food production by reducing crop yields.

• Selective breeding has positively impacted agriculture and food production by enhancing desirable traits in crops and livestock.

• Selective breeding has led to the extinction of many crop and livestock species.

• Selective breeding has had no impact on agriculture and food production.
