Artificial Selection

What is artificial selection?

• The process of natural selection in the wild

• The intentional breeding of plants or animals to produce desired traits.

• The practice of cloning animals

• The use of organic fertilizers in agriculture

Which of the following is an example of selective breeding?

• Breeding dogs for specific traits such as size or temperament.

• Breeding fish for faster swimming speed

• Breeding cats for specific fur color

• Breeding birds for better eyesight

What is the main goal of domesticating animals?

• To let them roam freely in the wild and live without human interference

• To use them for various purposes such as food, clothing, transportation, and companionship

• To use them as guards and protectors of the household

• To teach them how to perform tricks and entertain people

How has artificial selection contributed to crop improvement?

• Artificial selection results in decreased crop yield and quality

• Artificial selection allows for the breeding of plants with desirable traits, leading to improved crop varieties.

• Artificial selection only leads to the breeding of plants with undesirable traits

• Artificial selection has no impact on crop improvement

What is genetic modification?

• The process of altering an organism's habitat using biotechnology.

• The process of altering an organism's physical appearance using biotechnology.

• The process of altering an organism's genetic material using biotechnology.

• The process of altering an organism's behavior using biotechnology.

Which of the following is an example of genetic modification?

• Using pesticides on crops

• Breeding two different species of animals

• Inserting a gene from one organism into the DNA of another organism

• Mixing chemicals in a laboratory

What is the purpose of selective breeding in plants?

• To develop new plant varieties with improved characteristics.

• To prevent the growth of new plant varieties

• To reduce genetic diversity in plants

• To make plants less productive

How does selective breeding differ from natural selection?

• Selective breeding involves intentional breeding for specific traits, while natural selection is the process by which organisms with favorable traits are more likely to survive and reproduce.

• Selective breeding occurs in the wild, while natural selection is done by humans

• Selective breeding results in random genetic changes, while natural selection is purposeful

• Selective breeding leads to a decrease in genetic diversity, while natural selection increases it

What is the role of humans in artificial selection?

• Humans have no role in artificial selection

• Humans randomly select organisms for breeding

• Humans selectively breed organisms with desirable traits.

• Humans only breed organisms with undesirable traits

Why is artificial selection important in agriculture?

• To introduce harmful genetic mutations

• To create new diseases in plants and animals

• To reduce the yield of crops and livestock

• To breed plants and animals with desirable traits
