Selective Breeding and Mutations

What is selective breeding?

• Breeding specific organisms with desirable traits to produce offspring with those traits.

• Breeding organisms to create mutations in their offspring

• Breeding organisms randomly without considering their traits

• Breeding organisms to produce offspring with undesirable traits

Give an example of selective breeding in plants.

• Breeding sunflowers for increased height

• Breeding potatoes for resistance to diseases

• Breeding roses for specific colors or sizes.

• Breeding apples for specific flavors

What is a mutation?

• A new species of animal

• A change in the DNA sequence of an organism

• A change in weather patterns

• A type of plant

How do mutations occur?

• Exposure to sunlight

• Eating too much sugar

• Changes in the DNA sequence

• Wearing glasses

Explain the difference between natural selection and selective breeding.

• Natural selection is the process by which organisms with favorable traits are more likely to survive and reproduce, while selective breeding is the process by which humans intentionally breed organisms with desirable traits.

• Natural selection is the process by which organisms with unfavorable traits are more likely to survive and reproduce, while selective breeding is the process by which humans unintentionally breed organisms with undesirable traits.

• Natural selection and selective breeding are the same process, just with different names.

• Natural selection is the process by which humans intentionally breed organisms with desirable traits, while selective breeding is the process by which organisms with favorable traits are more likely to survive and reproduce.

What are the advantages of selective breeding?

• No impact on productivity, quality, and resistance to diseases and pests.

• Increased productivity, improved quality, and enhanced resistance to diseases and pests.

• Unpredictable results, decreased diversity, and increased vulnerability to diseases and pests.

• Decreased productivity, worsened quality, and reduced resistance to diseases and pests.

What are the disadvantages of selective breeding?

• Loss of genetic diversity, potential for increased susceptibility to diseases, and unintended negative traits

• No impact on genetic diversity, no change in susceptibility to diseases, and only positive traits

• Increased genetic diversity, resistance to diseases, and improved traits

• Decreased genetic diversity, reduced susceptibility to diseases, and intended positive traits

How can mutations be beneficial to a species?

• Mutations have no impact on a species

• Mutations can introduce new genetic variations that may provide a survival advantage in changing environments.

• Mutations only occur in non-essential genes

• Mutations always lead to harmful genetic variations

What are some examples of mutations in animals?

• Changes in eye color

• Mutations in plant species

• Alterations in the weather patterns

• Changes in coat color, size, shape, or behavior

Explain how selective breeding and mutations contribute to the diversity of living organisms.

• Selective breeding and mutations are not related to the diversity of living organisms

• Selective breeding and mutations have no impact on genetic diversity

• Selective breeding and mutations both introduce new genetic variations, leading to diversity.

• Selective breeding and mutations only lead to negative genetic variations
